Huawei EC1261-Modem in squeeze-No Frequent detection
Hi All,
I recently got a new Acer Aspire 5740 laptop and unfortunately, my Huawei HSPA modem EC1261 doesn't get detected as a modem (it does get detected as a USB mass storage device) by Debian Squeeze frequently. It works only once in while. But with my previous laptop (Acer Aspire 5583 LWXMi) it used to work every time I plug in without any issues. I didn't have to worry about anything. This old laptop had Squeeze too. I don't know what exactly is the issue with my new one. Since the Modem gets detected once in a while, I don't think its an hardware issue.
lsusb output is shown below. 1446 is the product ID for USB storage for the vendor ID 12d1. I understand that usb_modeswitch is the one who changes the product mode from USB storage to USB modem. The version of this package in the old and new laptop is the same. If I remember correctly, once when the modem worked with the new laptop, the product ID changed from 1446 to 140b. If anyone has any clue on why this is happening, please do let me know. Thank you in advance.
