Hi,
I have just tried the rc2-gregkh-1 patch on my 2.4.18 (SMP, devfs,
1.3GB) machine and I must report *disaster* with a USB mouse.
My machine has some interesting USB hardware:
- 2 UHCI 1.1 ports (motherboard)
- 4 OHCI/EHCI ports (OrangeMicro USB/Firewire combo card)
This means that the hotplug script loaded the uhci.o, usb-ohci.o and
ehci-hcd.o modules.
When I plugged the mouse into one of the UHCI ports, the box loaded
the input drivers and then locked up solid:
Mar 3 19:37:40 twopit kernel: hub.c: USB new device connect on bus4/1, assigned
device number 2
Mar 3 19:37:40 twopit kernel: usb.c: USB device 2 (vend/prod 0x45e/0x9) is not
claimed by any active driver.
Mar 3 19:37:40 twopit kernel: usb.c: registered new driver hiddev
Mar 3 19:37:40 twopit kernel: usb.c: registered new driver hid
Mar 3 19:37:40 twopit kernel: input0: USB HID v1.10 Mouse [Microsoft Microsoft USB
Mouse] on usb4:2.0
Mar 3 19:37:40 twopit kernel: hid-core.c: v1.8 Andreas Gal, Vojtech Pavlik
<[EMAIL PROTECTED]>
Mar 3 19:37:40 twopit kernel: hid-core.c: USB HID support drivers
And that was all she wrote. Not even SysRQ worked. I might have had to
move the mouse first before firework-time; I'm not sure.
For reference, the same USB mouse works fine on basic 2.4.18 with the
following patch:

uhci_packetout(td->info),
uhci_toggle(td->info) ^ 1);
This patch just fixes a UHCI regression between 2.4.17 and 2.4.18, so
it's not controversial.
I've noticed that this USB 2.0 patch might be going into
2.4.19... ooerr!
