[gentoo-user] U.V.C. Webcam Disconnects shortly after Registration
How's it going dudes? I bought a Logitech C270 webcam from Argos about a year ago, which, according to the LKDDb [1] and U.V.C. driver website [2], should work well on Linux. Despite working flawlessly until recently, some strange behaviour has appeared. When I connect the webcam, `dmesg` registers it as would be expected (timestamps omitted): usb 3-7: new high-speed USB device number 14 using xhci_hcd usb 3-7: New USB device found, idVendor=046d, idProduct=0825, bcdDevice= 0.12 usb 3-7: New USB device strings: Mfr=0, Product=0, SerialNumber=2 usb 3-7: SerialNumber: 9EEFE4E0 uvcvideo: Found UVC 1.00 device (046d:0825) input: UVC Camera (046d:0825) as /devices/pci:00/:00:14.0/usb3/3-7/3-7:1.0/input/input27 usb 3-7: set resolution quirk: cval->res = 384 However, about two seconds later, me having done nothing, the kernel ring buffer suggests it has been physically unplugs, and thus deregisters the device... USB disconnect, device number 14 I have tested this on another very similar machine, and this problem is not to be seen, and everything works perfectly; thus ruling out a hardware issue with the camera. Furthermore, no other devices---even other U.V.C. webcams---do not present with the same symptoms on my machine, in the same U.S.B. port; thus ruling out any issue with the physical port or motherboard controller. I have no idea how to triage this further. I feel like my head has been nailed to a coffee table by Dinsdale Piranha. Any tips? My kernel is 5.9.13-zen1, although this trouble presents identically on a vanilla kernel. Cheers. Hope everyone is remaining well.

[gentoo-user] problems with an ebuild for brltty
Hi. I have an ebuild for app-accessibility/brltty-6.2.ebuild -- I
copied it from the 6.1, but the install fails, it compiles OK. The
ebuild is attached for your convenience.
Here is what I get and what the developer told me.

Here is what the developer said:
> * !!! newins: Autostart/Udev/rules does not exist
That file has been renamed to device.rules. That's because there are
now two
ruells files - device.rules and uinput.rules. They should both be
installed.
Why doesn't gentoo just use brltty's make install-udev?
udev_newrules Autostart/Udev/rules 70-brltty.rules
It should be: Autostart/Udev/device.rules
Note that there's another file now that also needs to be installed:
Autopstart/Udev/uinput.rules newinitd
"${FILESDIR}"/brltty.rc brltty
>systemd_dounit Autostart/Systemd/brltty@.service
Note that there's a new systemd instance unit that also needs to be
installed:
Autostart/Systemd/brltty-device@.service
>systemd_dotmpfilesd "${FILESDIR}/${PN}.tmpfiles.conf"
I'm not sure of the precise syntax, here, but this file should be
installed as
brltty.conf (i.e. named after the package) when it's installed into
the
tmpfiles.d/ subdirectory.
There's also another systemd file, sysusers, which should be named
brltty.conf
(again named after the package) when it's installed into the
sysusers.d/
subdirectory.
>I wonder what to change to get this working?
Explained above. What I'm wondering, however, is why this is being
done outside
of the make file that brltty already comes to do all of this. Why not
just do:
make install-systemd install-udev
I should also make sure to mention that there are two more systemd
units -
brltty.path and brltty@.path - that also need to be installed.
Really, we provide make files that do all of these things. How can any
distribution ever get it right when it wants to try to get it all
right its own
way? Code duplication is never good!
Please bear with me -- although I have used gentoo for years, I have
not done much with writing ebuilds.
Thanks in advance for any suggestions.
And, Merry Christmas to all on this list, you folks have been a great
help over the years.

Re: [gentoo-user] Re: Is a USB-key-to-hard-drive-tap-dance-boot possible?
I see your problem, I think. You don't have your ESP mounted, so grub can't write the EFI files to it. You are likely trying to use grub with grub-install /dev/sda. That won't work for EFI. Try this (as root): mkdir /boot/efi mount -t vfat /dev/sda1 /boot/efi grub-install --target=x86_64-efi --efi-directory=/boot/efi grub-mkconfig -o /boot/grub/grub.cfg you MAY need to add --removable to the grub-install line. Some EFI setups prefer that.

[gentoo-user] Cannot emerge 32 bits version of gnome libraries
Hi, I have build failures for various gnome libraries. The errors happen when compiling the 32 bits versions, and seems to be due to "-m32" not being used for the C compiler. The errors are either the linker complaining about architecture mismatch, or glib static assertion errors about pointer sizes. I can see from the build log that the "-m32" option is missing. In particular, in the prepare phase, I see the following: C compiler for the host machine: x86_64-pc-linux-gnu-gcc (gcc 9.3.0 "x86_64-pc-linux-gnu-gcc (Gentoo 9.3.0-r1 p3) 9.3.0") C linker for the host machine: x86_64-pc-linux-gnu-gcc ld.bfd 2.34 C++ compiler for the host machine: x86_64-pc-linux-gnu-g++ -m32 (gcc 9.3.0 "x86_64-pc-linux-gnu-g++ (Gentoo 9.3.0-r1 p3) 9.3.0") C++ linker for the host machine: x86_64-pc-linux-gnu-g++ -m32 ld.bfd 2.34 So strangely it's present for C++ but not for C. Also, I can emerge other non-gnome multilib packages just fine. Has anyone encountered this before? Any tips for debugging that? Thanks, François-Xavier

AT decided that the other day was as good a time as any to let the DSL go down for a few days. AT made a huge mistake letting the whole community out here sit for days without service. With the new much faster and economical service coming, anyone who might have stayed with AT is now ready to switch. Bad thing is, almost every one out here depends on the internet to watch the weather and we had some storms come through overnight with no way to know what was coming. I just hid under the covers. Way to go AT You got a nice shovel, keep digging. ROFL My router has yellow connectors for routing and a blue connector going to the internet/WAN/whatever. My modem is similar except it is green for the telephone line. If I recall correctly all of those are supposed to be GB connectors, not that the modem could ever do that over the internet but it can between devices hooked to it. I disabled the wi-fi and such on the modem, not enough range anyway. Step away 30 feet or so, no signal. My router also has two USB plugs for sharing external hard drives or USB sticks. I'm not talking about that because I don't like hooking a drive up over USB. It never works well for some reason. According to the link below, I hook the NAS up to the router via ethernet and it is available for all devices connected to the router. I'd guess that I can also make it accessible to the internet to but I doubt I'll do that. If it is set that way by default, I'll google and find out how to disable that. Linky: https://www.linksys.com/us/support-article?articleNum=137552 I have a TP-Link router but figure it will work the same. I don't think I was to clear on the connection in earlier message. It was in my brain but didn't make it to the keyboard. lol Dale :-) :-) P. S. Now to catch up on all the emails. O_O

You're welcome. The command 'sha512sum -c' you ran succeeded in checking any sha512 hashes in the file and reported "OK". I just had a look at the contents of this file. The other lines, for which the sha512 check reports a "FAILED" warning use the whirlpool hash.
