[PARTIALLY SOLVED] maple mini com port not showing. URGENT

[arkabhowmick]

I just uploaded a nokia 5110 lcd sketch to maple mini via arduino ide.
i used pins 27,28,29,30,31 for spi connections.
After it was done uploading,
whenever i plugged in the maple mini to my computer, the com port is not being detected(no error is also being shown in com port device manager).
i hear 2 sounds one after another when i plug in the maple mini.(one for being detected and one for being plugged out).
Please help. URGENT.

Try a simple blinky sketch with serial output. If it works, then your software is the problem.
You should be able to upload if you press reset when the upload starts (check the Arduino message window).

Thank you very muchhhhhhh it is working..... when uploading sketch i pressed reset...and now the blink sketch works... thank you thank you...

Same problem here with libmaple core, blink works but serial USB don't.

With STM32GENERIC serial USB works.
Any ideas?

@vitor, how do you upload?
Have you tried to press reset at upload time, when the appropriate message appears in Arduino IDE?

[vitor_boss]

Yes, upload using DFU on 2.0 bootloader. windows says DEVICE_DESCRIPTOR_FAILURE
