Mucho timeouts on USB

Hi,

Just got a D-Link USB radio (R100) and I'm seeing lots of timeouts with
it. I've seen this through the last few 2.4.1+ and -ac+ kernels.

Current config:

Dual P3-500 w/ 512mb of RAM
Tyan Tiger 133 mobo with VIA chipset, onboard USB
Kernel 2.4.1-ac9 compiled with egcs-1.1.2

The only thing funky is that three devices are sharing an interrupt:

CPU0 CPU1
0: 216690 219652 IO-APIC-edge timer
1: 3564 3816 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
3: 7 20 IO-APIC-edge serial
5: 1017 1135 IO-APIC-level EMU10K1
8: 0 1 IO-APIC-edge rtc
11: 22978 22756 IO-APIC-level aic7xxx, eth0, usb-uhci
12: 64220 63272 IO-APIC-edge PS/2 Mouse
14: 12132 12810 IO-APIC-edge ide0
15: 3 10 IO-APIC-edge ide1
NMI: 436327 436327
LOC: 436151 436128
ERR: 0

The ethernet card is a 3Com 3c905, the SCSI card is Adaptec 7892B (19160
card). No problems with either as far as I can tell, but one of these
modules may not be playing nice with interrupt sharing.

The messages:
