Package: libusb-0.1-4 Version: 2:0.1.12-5 Severity: important Hi all, I am testing usb on SGI O2 (mips cpu, 64 bits kernel, 32 bits userland). This is something new and I am trying to document a problem with USB and libusb.
Using latest kernel from experimental 2.6.26-1-r5k-ip32 (previouses kernels did not support USB at all), we got many CONFIG_USB built into the kernel or as modules. Actually, I may use storage devices without any problem, but I cannot access devices via libusb. This means that "lsusb" tool does not list any device (beside internal hubs), while application like "sane" cannot access usb scanners via libusb. Please find attached what happens when I plug a 512Mb pendrive and then I replace it with a scanner. Kernel correctly manage the usb insertion/detection/removal, while libusb always display and empty list. Please also notice that /proc/bus/usb/devices correctly report all plugged devices. Moreover, when I plug in the scanner USB cable, udev detect it and change ownership of /dev/bus/usb/???/???. I recompiled more recent packages than what were shipped with etch, but I get the same behaviour. I used: libusb 2:0.1.12-12 udev 0.114-2 libsane 1.0.19-16 libsepol 2.0.30-2 libselinux 2.0.65-4 Thanks for your help, Giuseppe [EMAIL PROTECTED]:~$ sudo su - Password: sgi:~# tail -f /var/log/syslog& [1] 9348 sgi:~# Aug 4 19:11:22 sgi kernel: [17182202.312000] usb 3-2: new high speed USB device using ehci_hcd and address 3 Aug 4 19:11:22 sgi kernel: [17182202.460000] usb 3-2: configuration #1 chosen from 1 choice Aug 4 19:11:22 sgi kernel: [17182202.468000] hub 3-2:1.0: USB hub found Aug 4 19:11:22 sgi kernel: [17182202.468000] hub 3-2:1.0: 1 port detected Aug 4 19:11:22 sgi kernel: [17182202.588000] usb 3-2: New USB device found, idVendor=067b, idProduct=2515 Aug 4 19:11:22 sgi kernel: [17182202.588000] usb 3-2: New USB device strings: Mfr=1, Product=3, SerialNumber=0 Aug 4 19:11:22 sgi kernel: [17182202.588000] usb 3-2: Product: USB Embedded Hub Aug 4 19:11:22 sgi kernel: [17182202.588000] usb 3-2: Manufacturer: Prolific Technology Inc.
