Dale So it doesn't matter which slots the webcams are plugged into? - Grant I'm not 100% sure of this but I think it will try to connect sort of like a IDE drive or even a old dial-up modem does. It just tries to use the fastest speed it can get a stable connect at. It appears to try the new faster version first but if that doesn't work it switches to the slower speed and tries that. Because of my hardware, I have to use both on mine since some can only use the slow speed and some can use the high speed. As far as the actual connector itself, I'm pretty sure it doesn't matter at all. It's one chip that controls it all anyway. Just like the PCI bus, it has one chip and that's it. I know I have switched my printer and camera around several times and it works the same no matter how I connect it. Now if you have the new version USB with everything hardware wise, you may be able to disable the old version so that it has no option but to use the new fast one. That way you can get the fast speed or a error message that it isn't working. Keep in mind tho, if you have a junky cable, it will limit the speed a LOT. My printer would not use the new fast version with a older cable. It does with the new cable tho. My camera just plain don't work with the new version no matter what. You may want to get a good quality cable to test with too. Someone correct me if I am off base here. Dale You seem to be right on here Dale. usbview showed my printer connected to the 2.0 controller and a webcam connected to the 1.1 controller, so I unplugged the printer and plugged the webcam into it's slot and it still showed up under 1.1.

My webcams can't both operate on the 1.1 controller at the same time due to the bandwidth limitation of the 1.1 controller.

[gentoo-user] Kernel update messed up console encoding
Dear listmates, (I did try to use a more specific mailing list, and tried gentoo-admin, but it seems there's nobody around.) I recently updated my kernel from 2.6.17 to 2.6.27, and it seems that the new kernel causes the encoding of the console to behave weird: I used to use the default Unix encoding, i.e. iso-8859-1, because this was fine for German (now I want to stick to it because I have so much legacy material in that encoding). Now, when I type a string with Non-ASCII characters on the commandline, it looks normal, but when I redirect this to a file, the file command identifies the contents of that file (correctly, it seems to me) as UTF-8. When I boot the old kernel (which I kept), the same procedure results in a file identified as iso-8859-1 (and with accordingly fewer bytes). Here are the contents (the same sentence): Kernel 2.6.17: Ich kann es außerdem nicht ändern Kernel 2.6.27: Ich kann es auÃerdem nicht ändern I grepped the .config files for any options that might have a bearing on this. The only difference I found was in the first of these four lines: linux-2.6.17: # CONFIG_NLS_ASCII is not set CONFIG_NLS_ISO8859_1=y CONFIG_NLS_ISO8859_15=y CONFIG_NLS_UTF8=y linux-2.6.27 CONFIG_NLS_ASCII=y CONFIG_NLS_ISO8859_1=y CONFIG_NLS_ISO8859_15=y CONFIG_NLS_UTF8=y So I set $CONFIG_NLS_ASCII differently for the new kernel. But as far as I understand, these refer to the handling of file names (it's in the section file systems), and only specify what is supported, so I don't see how this could have an effect on console encoding. The only thing I am dead sure about is that the kernel itself must be the culprit, because when I boot the old kernel, this behaviour goes away. There is absolutely no change in the system otherwise. (The $UNICODE variable in /etc/rc.conf is set to no.) Can anyone give me a hint where to look what I have messed up? Emacs, which I sometimes like to use on the console, is particularly uncomfortable with this, and I seem to write confusing e-mails. Many thanks in advance for any hint, Florian

[gentoo-user] Gentoo on Intel Mac Mini?
I'm considering attempting to set up an Intel Mac Mini as a MythTV frontend. Right now I'm thinking I'll leave the internal drive alone and boot from net or from a USB flash drive. That way I can spin down the internal HD and save on power and noise (and the standard OS-X install is still there, so it can be trivially switched back to normal desktop use). I've been googling for info on running Linux on a Mac Mini, and there was fairly active discussion 3-4 years ago, but very little recent info. That leads me to either of two conclusions: 1) It can't be done and everybody gave up. 2) It's so trivial that people no longer need to ask about it. So, how hard would it be to do a USB or network-based Gentoo install for a recent Intel Mac Mini? -- Grant Edwards grante Yow! I want another at RE-WRITE on my CEASAR visi.comSALAD!!

The only difference I found was in the first of these four lines: linux-2.6.17: # CONFIG_NLS_ASCII is not set CONFIG_NLS_ISO8859_1=y CONFIG_NLS_ISO8859_15=y CONFIG_NLS_UTF8=y linux-2.6.27 CONFIG_NLS_ASCII=y CONFIG_NLS_ISO8859_1=y CONFIG_NLS_ISO8859_15=y CONFIG_NLS_UTF8=y So I set $CONFIG_NLS_ASCII differently for the new kernel. But as far as I understand, these refer to the handling of file names (it's in the section file systems), and only specify what is supported, so I don't see how this could have an effect on console encoding. The only thing I am dead sure about is that the kernel itself must be the culprit, because when I boot the old kernel, this behaviour goes away. There is absolutely no change in the system otherwise. (The $UNICODE variable in /etc/rc.conf is set to no.) Can anyone give me a hint where to look what I have messed up? Emacs, which I sometimes like to use on the console, is particularly uncomfortable with this, and I seem to write confusing e-mails. Many thanks in advance for any hint, Florian Genrally speaking: switch to utf-8! There are many tools which can convert your files automatically. To your issue: Well, there still is /etc/conf.d/consolefont which could mess up things. Or the locales... But the different bahavior of the two kernels is strange... Is CONFIG_NLS_DEFAULT different of the two kernels? Maybe it's also related to the kernel build in keymap... Maybe you should try the gentoo-user-de list, maybe there is someone whon ran into the same problem... HTH Sebastian -- Religion ist das Opium des Volkes.

The controller, though, I'm pretty sure is able to allocate more than enough overall bandwidth to the pair. Based on your original remarks that one of them isn't functioning, I worry more that there's a problem with the driver for the camera itself that somehow breaks with two of the same camera present, broken udev rule somewhere that's not creating the device for the second camera, or... *something* more along those lines, rather than an issue with the on-chip implementation of your usb controller. -- Poison [BLX] Joshua M.

It would be like me wanting my old dial-up modem to connect to my ISP at 256K/s. It can't do that because it was not built to do that or has the hardware to do it either. Not to mention that my ISP would not be happy either. I suspect that sort of like my IDE bus, when I have a old drive on the same cable as a fast one, it is slower because of all the negotiating that goes on between the different devices. I may be wrong but I don't think you are going to be able to get two cameras to work unless they are both USB 2.0 or on a separate chip such as a expansion card. The camera is your limiting factor from what I understand. Dale :-) :-)
Re: [gentoo-user] Gentoo on Intel Mac Mini?
I did not try recently. 3-4- years ago it may still have been Linux PPC. Now it is MacTel so it mainly should be a question of supported hardware and booting.

i used gentoo to run off vmware fusion on an intel mac. saved me a lot of headache. it works. i use it as a development/test bed.

Re: [gentoo-user] Gentoo on Intel Mac Mini?
It is done often. Writing this on an 24 Intel iMac running Gentoo w/ kde. Just a few gotchas that I ran into: 1. The 2008.0 livecd's version of grub doesn't have the Mac partition patch. Simple update of portage and then grub fixes this. 2. Nvidia binary drivers seem to have a bug that will turn off the screen everytime you either close X11 or switch to a VC. The screen comes back on when you go back to X by CTRL+Fn unless you have shutdown X11. If that is the case, then you have to restart it by typing blindly or ssh'ing in from another machine. I haven't found a fix for this yet. Not sure if this pertains to the mac mini they might be using ATI. Good info at: http://en.gentoo-wiki.com/wiki/Apple_Macbook_Pro If you plan on installing to the hard drive I recommend keeping a small OSX partition (for firmware updates and stuff from apple) and using rEFIt as a boot manager. http://refit.sourceforge.net This is how I have it set up and its working well.
