Hello everyone, this is a bug report with a suggested patch included. Summary: usb_host_scan() in usb-linux.c doesn't handle the logic correctly when looking for different places to find bus/usb/devices. Environment: qemu revision 5499 on slamd64 (slackware) 12.1 Symptom: no "host:" usb devices are available at all on any system where /proc/bus/usb/devices exists. Diagnosis: the else clause for the USB_FS_SYS case is wrong.
Thanks for narrowing this down. Please include a Signed-off-by so we can include your patch. Regards, Anthony Liguori
