I have found the problem: the glibc on mips only allow 8-bits for the minor, and strips the upper bits. That's why it works when your device appears on bus 1. This bugs has been fixed very recently upstream. I am therefore reassigning this bug to the libc6 package. > From that moment, I cannot use any USB device via libusb: when trying again > to identify the device I get a lot of "Operation not permitted" and "Operation not permitted" messages are normal, given that you are not root. Also some operations are not allowed on some USB devices, it is safe to ignore them. > "Connection timed out": This looks more problematic, please first try to run sane-find-scanner as root, to make sure it is not a permission issue. If it doesn't work, it looks like a kernel issue. Also the device can be in autosuspend mode, try to tweak /sys/bus/usb/devices/usb1/power/autosuspend . -- .''`.
