Is it possible to modify USB device descriptors? RRS feed

  • Question

  • More specifically, I'm interested in changing the value of bcdUSB from 0x0110 to 0x0200 to allow a USB 1.1 mouse to support USB 2.0. Can this be done?

  • If you want the hcd to see the modified value, no, this is not possible. Of you want the hid driver to see the modified value, you can write a lower filter under hidusb, capture the appropriate urb and modify the result
