Motorola has apparently broken the USB functionality on the new Razr2 V9m Bronze.
We have an "older" model, all of about 3 months older, which works correctly. Using lsusb, the older model reports as:
Bus 004 Device 028: ID 05c6:1000 Qualcomm, Inc.
when set to connect as a USB drive, and as:
Bus 001 Device 005: ID 22b8:2b24 Motorola PCS
when set to connect as "Modem/COM".
The new Bronze phone appears identically to the older one when set to connect in either "Modem/COM" or its new "Media Sync" mode. But when set to connect in USB drive mode, it fails to produce a lsusb entry, and the system can not see it. The phone reports "Connected as USB drive", and the battery starts charging from the USB. So the phone knows that it is connected despite the fact that the computer can't see it.
We swapped the micro-SD cards between phones, and tried the phones on two different Linux machines, one running Kubuntu Feisty,the other running Kubuntu Hardy. The fault was conclusively determined to be with the new phone.
We then took the phone back to the phone company store where it was purchased. It works fine as a USB drive when connected to a Windows machine. Motorola tech support is predictably clueless, saying;
"Double click on My Computer..."
after being told that we were using Linux.
How is this possible that Windows can see this device, yet Linux can not?
