Target detected as "unknown device" -imx6

[rajesh7989]

Hi,

   I am using MfgtTool2 to flash a target. When the target enters boot mode windows recognizes as a unknown device and the Mfgtool2 shows "No device connected".

Can someone help me on this issue. Thanks in advance.

Hi Rajesh

some problems may be with Windows 7 64 bits or USB 3.0 controller

(enumeration problem may be related to USB3.0 controllers (XHCI) and the

associated driver. Was found that the command sequence for enumeration on a

XHCI controller is different from enumeration on an EHCI controller). 

One can try other PC using Windows XP or 32bit Windows 7 or disable USB 3.0.

Best regards

igor
