Red Hat Bugzilla – Bug 208624
High speed USB HID devices not working
Last modified: 2007-11-16 20:14:54 EST
Description of problem:
High speed (USB 2.0) HID devices aren't working. Specifically this was seen
with a new USB 2.0 Avocent KVM dongle.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Connect Avocent USB 2.0 KVM dongle.
2. Boot system.
3. Note that keyboard & mouse don't work.
Keyboard & mouse don't work (unless you unload the ehci-hcd driver).
Keyboard and mouse should work.
Unloading the ehci-hcd driver will allow you to use the keyboard.
The problem is that the usbhid driver (in hid-core.c) is modifying the
interrupt URB interval for high speed devices, and then calling
usb_fill_int_urb, which applies the same modification to the already-modified
interval value, resulting in a ridiculous value, which the ehci driver won't
even schedule. The attached patch fixes the issue.
