Question:
My pcmtuner USB dongle not accessible. The dongle stops communication and threw an error USB not accessible.
Any Solution?


Solution:
You update pcmflash. NEVER update pcmflash.
Remove complete from pc and reinstall software.
The pcmtuner hardware won’t be locked.
How to fix it if update pcmflash by mistake?
- Delete current pcm flash ONLY.
- Install pcm-flash 1.2.0 application here (disable anti-virus program)
