I'm not seeing this behaviour. My CAPS LOCK works fine, with UHCI controller
and Microsoft Natural Keyboard Pro.

I'm using UHCI-alt, and this is the detail on the keyboard:
T:  Bus=01 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#=  3 Spd=1.5 MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=045e ProdID=001d Rev= 1.11
S:  Product=Microsoft Natural Keyboard Pro
C:* #Ifs= 2 Cfg#= 1 Atr=a0 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=01 Prot=01 Driver=hid
E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl= 10ms
I:  If#= 1 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=00 Prot=00 Driver=hid
E:  Ad=82(I) Atr=03(Int.) MxPS=   3 Ivl= 10ms
Do you have the same device?

and this is my controller (from lspci -vv):
00:07.2 USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 01) (prog-if
00 [UHCI])
        Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping-
SERR- FastB2B-
        Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort-
<MAbort- >SERR- <PERR-
        Latency: 64
        Interrupt: pin D routed to IRQ 9
        Region 4: I/O ports at fca0 [size=32]

Can you try the hardware on another machine? Do other devices work?
