Title: usb_modeswitch not run correctly for 3G dongle Status in usb-modeswitch package in Ubuntu: Confirmed Bug description: I am using a laptop (Asus N56VZ) with Ubuntu 14.04 LTS (recently upgraded from 12.04 LTS) and until recently none of my 3G USB dongles worked (I have a few). Note that the very same problem occurred on 12.04 and I upgraded early hoping for this issue to go away. It didn't. After investigation, it seems that usb_modeswitch is't doing its magic: My test dongle is a Huawei Technologies Co., Ltd. ID 12d1:14c1 According to the udev rules and the usb_modeswitch data I could dig up, the product ID should switch to 14c6 to make it work correctly. A file named "12d1:14c1" IS in the tgz package of usb-modeswitch-data, but nonetheless this is all I see in /var/log/syslog when I plug the dongle in: =================================================================================== May 1 00:44:49 rramondalap02 kernel: [ 54.336137] usb 3-1: new high-speed USB device number 3 using xhci_hcd May 1 00:44:49 rramondalap02 kernel: [ 54.354566] usb 3-1: New USB device found, idVendor=12d1, idProduct=14c1 May 1 00:44:49 rramondalap02 kernel: [ 54.354570] usb 3-1: New USB device strings: Mfr=3, Product=2, SerialNumber=0 May 1 00:44:49 rramondalap02 kernel: [ 54.354571] usb 3-1: Product: Vodafone Mobile Broadband (Huawei) May 1 00:44:49 rramondalap02 kernel: [ 54.354572] usb 3-1: Manufacturer: Vodafone Group (Huawei) May 1 00:44:49 rramondalap02 kernel: [ 54.355682] usb-storage 3-1:1.0: USB Mass Storage device detected May 1 00:44:49 rramondalap02 kernel: [ 54.355814] scsi7 : usb-storage 3-1:1.0 May 1 00:44:49 rramondalap02 kernel: [ 54.355879] usb-storage 3-1:1.1: USB Mass Storage device detected May 1 00:44:49 rramondalap02 kernel: [ 54.355985] scsi8 : usb-storage 3-1:1.1 May 1 00:44:49 rramondalap02 mtp-probe: checking bus 3, device 3: "/sys/devices/pci0000:00/0000:00:14.0/usb3/3-1" May 1 00:44:49 rramondalap02 mtp-probe: bus: 3, device: 3 was not an MTP device May 1 00:44:50 rramondalap02 kernel: [ 55.354598] scsi 7:0:0:0: CD-ROM Vodafone CD ROM (Huawei) 2.31 PQ: 0 ANSI: 2 May 1 00:44:50 rramondalap02 kernel: [ 55.355275] scsi 8:0:0:0: Direct-Access Vodafone Storage (Huawei) PQ: 0 ANSI: 2 May 1 00:44:50 rramondalap02 kernel: [ 55.356963] sr1: scsi-1 drive May 1 00:44:50 rramondalap02 kernel: [ 55.357074] sr 7:0:0:0: Attached scsi CD-ROM sr1 May 1 00:44:50 rramondalap02 kernel: [ 55.357135] sr 7:0:0:0: Attached scsi generic sg3 type 5 May 1 00:44:50 rramondalap02 kernel: [ 55.357264] sd 8:0:0:0: Attached scsi generic sg4 type 0 May 1 00:44:50 rramondalap02 kernel: [ 55.359620] sd 8:0:0:0: [sdc] Attached SCSI removable disk May 1 00:44:50 rramondalap02 usb_modeswitch: switch device 12d1:14c1 on 003/003 =================================================================================== Now I found a way to make it work: sudo usb_modeswitch -v 12d1 -p 14c1 -M '55534243123456780000000000000011062000000100000000000000000000' After some seconds pass the dongle is correctly switched to the new ProductID and works as intended. I thought the issue was with the usb-storage delay (as per /etc/usb_modprobe.conf ) but even after configuring SetStorageDelay=6 I got no change in behavior. Still, I hope that someone more accustomed to the internals of usb_modeswitch will find a solution, given that a workaround is already available.
