Receiving bytes in wrong order or replaced bytes #506

Hi,

Sometimes a byte I receive is replaced, by what appears to be a 'double' byte, for example I receive '... 31 00 00 00 78 ...' instead of '... 31 36 00 00 78 ...'. Do you have any idea why this could be the case?

I am using using the CdcAcmSerialDriver for the Device I am connecting. If I connect this device to a Windows PC the Cdc-driver is also used, I detect no problems when using Windows.

if the serial device is powered over USB, it might work less stable when powered by the Android device

I now have the device powered from a different source, with enough juice, but the problem still remains.

It looks this is a Linux driver problem.
