That is right, also Usbview doesn't show any Configraution Descriptors, just
Device and Endpoints.
I started some test with the USB Command Verifier Tool suggested by Tim and
Indeed it shows some Errors.
I still have to get familiar what the tool is saying to me, up to now I have 3
Items:
- It says that I have no Configuration and I should have at least One
Configuration
- there is something with some BOS Descriptors, which are not available on
Full Speed, but t least some
error Message should be returned
- I am consuming current, and the Configuration is that I shouldn't
(which is indeed a wrong setting, but I think not the cause)
Now I am wondering if I could at least reproduce what is wrong also on my linux
system,
I have no windows System available where I can work on the Embedded device.
Does anyone know some Linux USB Device Test tool?
On Linux lsusb -d16d0:05be -vvv gives following, which displays the Config
descriptor or?
