USB has become very unstable since I have ugrade the firmware from 3.7.7 to 3.8.11 on my TSU7000. It is to the point that I can not program the TSU device.

I upgraded to 2.1.4.0 PPENG at the same time.

I have reinstalled the USB driver per Lyndel well laid out instruction in this post. I have to boot the computer down to get the USB to work now and it typically takes 2 or 3 communications to the TSU7000 and then the USB connection hangs and won't return unless a reboot of the computer occurs.

I was have some instability issues with the USB prior to the ugrading of software and firmware which is why I did the upgrade hoping that the USB might dissappear unfortunately it has only got significantly worse.

The USB physical connection appears to be recognised as there is no yellow explanation mark in device manager. When it hangs and I try and send anything to via the USB port I get "Communication with this device has failed. Please try again. (0300)"

Any suggestions would be gratefully recieved.

Thanks,

Fleetz
