Hey all, I ran into a snag I haven't been able to take care of yet while trying to get a driver made for my edgeport device. I am hoping for some guidance, so I'll do my best to post what I've read and done to make it easier to help me.(Plus I don't want anyone thinking I am posting here blindly without some extensive code and google reading)... I haven't been able to get my hands on any documentation for the device. I've tried to contact the author of the linux driver, but he said he didn't have any documentation and he only worked on the older models that didn't have the TI chipset.. So I attempted to contact the other names listed in the sources in the linux driver, but nobody else responded... To make a long story somewhat short, here is a link to the sources I have been looking at while trying to write my OpenBSD driver: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/usb/serial/io_ti.c;h=d4cc0f7af400d0133653e4e0515b25a131e2a37f;hb=HEAD Here is a link to my main file uep.c: http://pastebin.ca/1730689 Here is a link to uep.h: http://pastebin.ca/1730690 Here is a link to a dmesg after connecting my device and attaching my new driver: http://pastebin.ca/1730693 I've added a section to the files.usb file in /usr/src/sys/dev/usb for my new driver as follows: # Inside Out Edgeport deviceuep attachuep at uhub filedev/usb/uep.cuep I do not know for a fact this is correct, I may be wanting to use ucom(I'm hoping I can) later.. To finally get to my problem.. I am trying to read the manufacturing information off of the device.. but every time I call usbd_do_request I get error 11 returned back to me meaning 'NO POWER'.. I don't quite understand why I'm getting this message.. The other devices I've looked at don't do anything special before trying to read memory from the device, nor does the linux driver as far as I can tell. I've been reading uberry.c, umsm.c, and uvideo.c trying to find out the order in which the usbd_* functions are called, but it doesn't appear that I am doing anything special or different in my driver that would make it not work.. furthermore.. I've read through the usbd_do_request_flags_pipe function inside usbdi.c, and I can't see anywhere in the function where it returns USBD_NO_POWER.. so I am confused as to why i'm getting that message.. the only function that has a possibility of returning NO_POWER as far as I can tell is the usbd_set_config_index function. I hope this email has provided enough correct information to allow someone smarter than myself to tell me what I am not doing correctly.. If there's anything that I left off, please let me know and I will get whatever information is necessary. Thank you all for your time, I appreciate it.

Inside Out Networks Edgeport USB Serial Adapters
Hello all. I was wondering if anyone has worked on or is working a driver for the USB Serial Adapters made by the company Inside Out Networks called Edgeports? I see the device(s) listed under /usr/src/sys/dev/usb/usbdevs file, but I see no reference to them anywhere else... I'd like to attempt to get this device working under openbsd if it's possible, and was looking into what it would take to do so - I just wanted to make sure that nobody else was doing the same thing so as not to duplicate work. P.S. If anyone is willing and has the time, could you please contact me off-list about potentially being a sort of 'mentor' while I try to get this device working? I've read through some of the similar device drivers (uticom, uchcom, ex..), but truth be told I'd feel better off if somone else could provide some sort of guidance.. P.P.S I couldn't find support for the device in freebsd or netbsd, but linux appears to have a driver for it. The device also requires firmware be sent to it for it to work, which appears to be GPL licensed from the manufacturer - is this a problem? Thank you all. --Brad
Re: Inside Out Networks Edgeport USB Serial Adapters
I could have qualified the product(s) I am talking about better, I'm sorry. The device that I am referring to is http://www.digi.com/products/usb/edgeport.jsp There are several variations of the product, but the ones that I am interested in are the Edgeport/2+2i and the Edgeport/8 devices.. The first one listed as follows from openbsd -current (It detects nothing really..) ugen0 at uhub2 port 2 Inside Out Networks Edgeport/2+2i rev 1.00/1.00 addr 3 Again - Thank you all for your time. --Brad

Secondly, if the firmware is GPL, this is a problem since GPL is not compatible with BSD. On top of that the firmware is a sort of binary blob, which will never be used in any OpenBSD system. Your best bet is a clean-room reverse engineer. Sorry I couldn't be more helpful. -- Aaron Mason - Programmer, open source addict I've taken my software vows - for beta or for worse
Re: Inside Out Networks Edgeport USB Serial Adapters
Aaron Mason On top of that the firmware is a sort of binary blob, which will never be used in any OpenBSD system. Nonsense, binary firmware/microcode images are perfectly acceptable in OpenBSD, so long as the redistribution terms are clearly defined and suitable. Take a look in /etc/firmware. Binary-only *drivers* however are not acceptable, these would have to be loaded into kernel space.. performing all sorts of black magic that would complicate development. In this case, I found a site which seems to indicate a few models require a separate driver.. however it also indicates that later models use a TI-based chip, perhaps it might be possible to adapt the uticom(4) driver? http://www.kroah.com/linux/usb/edgeport/ No clue. -Bryan.

Nonsense, binary firmware/microcode images are perfectly acceptable in OpenBSD, so long as the redistribution terms are clearly defined and suitable. That's completely true. If the redistribution terms make the firmware become just free data, then we can distribute it, and use it. Binary-only *drivers* however are not acceptable, these would have to be loaded into kernel space.. performing all sorts of black magic that would complicate development. Completely true.

Get it working, and get back to us.
