View Full Version : [Resolved] Huawei E303C Datacard is not detecting in new MacBook Pro (Mountain Lion OS)

Sep 29, 2012, 03:01 PM
I am not able to use my Huawei E303C Datacard with new MacBook Pro 13" i7 Mid 2012 model (Mountain Lion OS). :(
When I insert Datacard in USB, green light keeps blinking, But Mobile Partner app (Huawei E303C Datacard default app) says "Device not found". Even if I keep it connected for more than an hour.
This Datacard is working all fine in iMac 2010 (Mountain Lion) and MacBook Pro 2011 (Snow Leopard).

Please help,

Thanks to the USB hub, Now Huawei E303C Datacard is working all fine in my new MacBook Pro 13" i7 Mid 2012 model. :)
For experiment purpose, I purchased one USB 2.0 hub (Unknown Chinese model).:confused:
I connected Datacard to USB hub and USB hub to MacBook Pro USB port.
Hurray!! Datacard is detected by MacBook Pro.:apple:

So, the problem is with MacBook Pro's new USB ports (USB 2.0 and 3.0 integrated) and Huawei E303C Datacard.
It is a hardware support issue with Huawei E303C Datacard.

Enjoy :)
