BB-CH340T HARDWARE PROBLEM

[Orvol]

Hello.

I bought this usb->serial chip from Olimex (BB-CH340T) and when I connect it to the computer, it just gives me message:

Windows stopped the device because it reported that there was a problem. (Code 43)
The USB device descriptor request failed.

I have tried everything with driver -> no solution. I think there is a hardware faile.
Can anyone please help me to find out where the problem is?

Thanke you in advance.

Lovro
