tiglusb cable error> ticables: err: usb_claim_interface


When running TiLP I'm trying to get it to use my TI USB cable (Grey link), using the driver that comes with the 2.4.27 kernel. I'm trying to run this as root now, just so I know if I can get it to run at all (if I can get it to run while I'm root, I can figure out how to make it run when I'm logged in as a normal user)

Here's the output when I try to select the Grey Link on Port 1 in TiLP:

Code:
ticables: getting method from resources (automatic):
ticables:   check for lib-usb usability:
ticables:     usb filesystem (/proc/bus/usb): mounted

ticables: err: usb_claim_interface (could not claim interface 0: Device or resource busy)
Any ideas?
Here's my /proc/bus/usb/devices part for the cable:
Code:
T:  Bus=02 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  3 Spd=12  MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0451 ProdID=e001 Rev= 1.03
S:  Manufacturer=Texas Instruments Incorporated
S:  Product=TI-GRAPH LINK USB
C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=tiglusb
E:  Ad=81(I) Atr=02(Bulk) MxPS=  32 Ivl=0ms
here's the /proc/bus/usb/drivers:
Code:
         usbdevfs
         hub
  0- 15: usblp
         usb-storage
         usbmouse
 96-111: hiddev
         hid
         tiglusb
