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 device uep attach uep at uhub file dev/usb/uep.c uep 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.
