I'm trying to program an imx6s over serial download mode, however I'm having no success getting my machine to recognize the device..  in Windows, the VID/PID is 0x0000 / 0x0000 and it's just "unknown device".  In Linux, the following appears in dmesg:

 

[  881.659326] usb 5-2: new low-speed USB device number 2 using ohci-pci

[  881.799161] usb 5-2: device descriptor read/64, error -62

[  882.042878] usb 5-2: device descriptor read/64, error -62

[  883.449250] usb 5-2: new low-speed USB device number 5 using ohci-pci

[  883.856789] hub 5-0:1.0: unable to enumerate USB device on port 2

 

On this board, we have not brought USBOTG out to the microusb, only USB-UART.  Will the serial-downloader not work over USB-UART alone?
