Using two identical USB devices on an Embedded ARM running debian


I have been attempting to control two identical usb cameras from my TS-7300 built by technologic systems that operates with Debian Linux. Drivers have been written to connect to the cameras individually, but in order for them both to get recognized one must be unplugged (run the drivers) then plug in the other and then run the drivers again. This means the board is properly assigning the hardware when the identical devices are not connected simultaneously. Is there a way to tell the hotplug system to recongnize them as different devices when they are connected simultaneously?

What exact distro (apart from just "debian"), and kernel are you running?

Thanks.

Your distro is old. Debian are up to 4.0 now AFAIK

I don't think I can help you as udev was only introduced in the 2.6+ kernels. Somebody correct me please.

udev was designed to sort out exactly the sort of problem you are experiencing.

Maybe it is time to bite the bullet and upgrade?

I wish it were that simple. The distribution and all its packages are made for ARM by technologic systems (embedded ARM) and they dont have the later versions working!
