Just wondering what is the minimum kernel version to ignore the device for usb-storage, I am running Ubuntu 12.04 (kernel 3.2.0-24) and it still does not ignore the device. On the other hand, it is possible to manually detach the driver using the instruction from Alan Stern. +++++++++ From Alan Stern ++++++ http://libusb.6.n5.nabble.com/How-to-dump-HID-report-descriptor-under-Linux-tp5971p5973.html You can detach and attach drivers by hand. To unbind hiddev from a device: cd /sys/bus/usb/drivers/hiddev ls Find the filename for the interface you want to unbind. Interface filenames have the form B-P:C.I where B is the bus number, P is a string of port numbers separated by periods, C is the configuration value, and I is the interface number. Having found the filename for the interface you want to unbind, do echo -n interface-filename >unbind To re-attach the driver, do echo -n interface-filename >bind ++++++++++++++++ For the usb-storage, it is similar. mcuee@GX620Ubuntu:/sys/bus/usb/drivers/usb-storage$ ls 5-2:1.0 bind module remove_id uevent unbind mcuee@GX620Ubuntu:/sys/bus/usb/drivers/usb-storage$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 005: ID 148f:3070 Ralink Technology, Corp.
