Re: Serial Port and USB on WINCE 6 R2



Which UART port are you using for debug output?
The FFUART might share the same pins with single end USB signals which is
for connecting external USB transceiver especially when OTG driver is
included.

Other information:
I copy the backup file regarding USB from the last update to the system a
regenerate the Kernel, all now is working fine, so i suppose there is a
bug in the new versions of USB source files.

Hi, i have found a strange behaviour regarding USB and Debug Serial.
I have this situation: A Serial Port (PXA270 STUART) I use for the debug
output string (so it's not a vaible as a COM port in the OS Design) and
the USB Function working as RNDIS driver.
I found that from R2 of Windows Embedded CE (using also the 21 Novembar
update) when i unplug the USB my serial port doesn't work any more, i see
strange bytes over it (like when it works at a wrong baudrate). If i
Re-plug the USB the debug serial port strats working again. I tried to
boot my system without the USB and thef debug serial doesn't work again.
Obviously this error doesn't appear before the R2.
Any information?
