Dear all:

  I am using 3G wireless card on Blackfin. The platform is BF547-0.4 and the uclinux kernel version is uclinux-dist-2009R1-RC6.

  The problem is that HUAWEI E1750 can't be recognized but it can be done by PC or TI platform. However, the other types of cards can be recognized. But this 3G wireless can be recognized  and the other types of cards can not be recognized through USB HUB(use USB HUB power or not use USB HUB is the same condition).

 

  When insert the card, the error messages appear:

  usb 1-1: new high speed USB device using musb_hdrc and address 2

  hub 1-0:1.0: unable to enumerate USB device on port 1

  usb 1-1: new high speed USB device using musb_hdrc and address 3

  hub 1-0:1.0: unable to enumerate USB device on port 1

  usb 1-1: new high speed USB device using musb_hdrc and address 4

  hub 1-0:1.0: unable to enumerate USB device on port 1

  ...

  usb 1-1: new high speed USB device using musb_hdrc and address 126

  hub 1-0:1.0: unable to enumerate USB device on port 1

  usb 1-1: new high speed USB device using musb_hdrc and address 127

  hub 1-0:1.0: unable to enumerate USB device on port 1

  usb 1-1: new high speed USB device using musb_hdrc and address 2

  hub 1-0:1.0: unable to enumerate USB device on port 1

  usb 1-1: new high speed USB device using musb_hdrc and address 3

  hub 1-0:1.0: unable to enumerate USB device on port 1

  ...

 

  The error messages can't stop,the cycle continues.

 

 

Thanks
