Device: EV2300
MFR: Texas Instruments
OS: Windows 2K
Symptom: USB device you are trying to connect to the VM is being used by another process.. Wait 5-10 seconds, then try to connect the device again.
Affects: causes guest OS and Mac OS to be very slow
I think is caused by Parallels not handling suprise removal properly. This device is a custom device that has its firmware loaded over USB. This loading works.
Once FW is loaded the device resets itself and begins running the new firmware. When the new firmware runs it disconnects from the USB automatically and then reconnects to the USB with a new PID/VID.
This second device is never enumerated (I can tell because I put debug LEDs in the device and the LED that blinking is the one indicating that the FW is waiting to be enumerated).
