It's low risk as it is known to work properly with most Huawei devices already; and only affects users of such devices. The E220, among others, remains one of the most common 3G modems available. [REGRESSION POTENTIAL] Low; this patch changes probing for Huawei devices only, and has been tested successfully with good support for the affected devices after the patch is installed, as well as unchanged behavior for many other devices (tested by cyphermox with a E1831 too). [TESTING] Requires Huawei 3G modem; needs to be the E220 or E1550 model for successfully testing the resolution of this issue. Testing with other Huawei devices is useful as control. Devices from other manufacturers are unaffected. ======= I'm using Ubuntu in my HP Pavilion dv6745tx laptop. I cannot connect the Huawei E220 usb modem since 11.10 beta1 (now I'm in beta2). There is no problem in natty.
