My Linux kernel version is 3.10.14 and I am using libusb-1.0.21 . I cross compiled it for mipsel-linux on my router for usb modem. when I try to run usb_modeswitch I got the following error : Error: Failed to initialize libusb. LIBUSB_ERROR_OTHER (-99) I found there is no entry /proc/bus for the attached usb modem. Can anybody tell me what to do resolve this issue.

I will be very thankful to you.

  • Can you please share the output of 'lspci | grep USB' – Karthik Balaguru Dec 17 '16 at 18:09
  • # lspci 00:00.0 Class 0604: Device 0e8d:0801 (rev 01) 00:01.0 Class 0604: Device 0e8d:0801 (rev 01) 01:00.0 Class 0280: Device 14c3:7662 02:00.0 Class 0280: Device 14c3:7662 – Pankaj Charpe Dec 19 '16 at 05:00
  • # lspci | grep USB is giving nothing but lspci is giving the following output 00:00.0 Class 0604: Device 0e8d:0801 (rev 01) 00:01.0 Class 0604: Device 0e8d:0801 (rev 01) 01:00.0 Class 0280: Device 14c3:7662 02:00.0 Class 0280: Device 14c3:7662 Also in the lastest kernel-3.10.14 /proc/bus/usb is not creating for usb dongle ,due to which libusb can't able to read and the usb_modeswitch is not working. – Pankaj Charpe Dec 19 '16 at 05:04
