I agree that this would be a useful enhancement to the uhci_hcd driver.
For example:

CPU0
0: 183247514 XT-PIC timer 0/47514
1: 67096 XT-PIC i8042 58/67096
2: 0 XT-PIC cascade 0/0
8: 82425669 XT-PIC rtc 0/25669
10: 163607273 XT-PIC uhci_hcd, EMU10K1 0/7273
11: 1912890 XT-PIC uhci_hcd, eth0 0/12890
12: 0 XT-PIC uhci_hcd 0/0
15: 244330 XT-PIC ide1 0/44329

The front panel USB port shares an interrupt with the sound card, the
rear with eth0. Fome some of my testing it would be helpful if these
just had numbers that I could mentally associate with a USB port. Right
now I have to move the mouse and watch the interrupt count.

Agreed, this bug should be fixed either way.
