I bought one of these cheap USB - MIDI cables on the market. And voila out of the box it worked in Linux Mint 8 and in Linux Ubuntu 9.10. Other versions aren't tested bij me.
I also wanted to use it in Windows XP, but that wasn't possible. The cable was seen and installed, but not visible in the MIDI menu of Cakewalk 9 ( I know it's old, but it does the job I want it to do). In Windows Vista everything went OK.
I fount this solution:
It is a conflict between the driver of a logitec webcan and the driver of this midicable. I had to Manually delete the UpperFilters and LowerFilters registry values. (maybe only one exists at your place)
To Manually delete the UpperFilters and LowerFilters registry values, follow these steps:
1. Start Registry Editor (Regedit.exe).
START > RUN > (Type) REGEDIT (and hit ENTER)
2. Locate the UpperFilters and LowerFilters value under the following key in the registry
3. Export the keyvalue and on the Edit menu, click Delete, and then click OK.
Now you have to UNINSTALL THE USB AUDIO DEVICE
Control Panel --> Hardware --> device manager --> in the hardware menu --> sound video and games --> USB audio divice (choose the proper one if you've got more than one),
UNPLUG the cable, AND REPLUG IT AGAIN
VOILA !!!! WORKING !!!!
