Huawei Gobi 3000 not detected
Last modified: 2011-10-12 23:50:48 UTC
I have a Huawei Gobi 3000 device that has a GSM firmware loaded and provides 3 ttyUSB interfaces via qcserial. I can connect and use the device via pppd without a problem but modemmanager cannot detect the device. Running on Debian Sid with modemmanager version 0.5-1 The serial device that pppd works with is ttyUSB1. Looking over the code it seems that the Huawei plugin attempts to handle the device and goes into a loop because the 0 interface of the usb device is not linked to a tty device and the plugin expects it to show up. If I read the code correctly, I don't think the Huawei plugin should handle this device, maybe the Gobi or generic gsm would work. Here is the output I get when running modem-manager --debug modem-manager[6245]: <info> [1316615687.378757] [main.c:167] main(): ModemManager (version 0.5) starting... modem-manager[6245]: <info> [1316615687.383918] [mm-manager.c:120] load_plugin(): Loaded plugin Option High-Speed modem-manager[6245]: <info> [1316615687.384393] [mm-manager.c:120] load_plugin(): Loaded plugin Gobi modem-manager[6245]: <info> [1316615687.384854] [mm-manager.c:120] load_plugin(): Loaded plugin Option modem-manager[6245]: <info> [1316615687.385291] [mm-manager.c:120] load_plugin(): Loaded plugin MotoC modem-manager[6245]: <info> [1316615687.385729] [mm-manager.c:120] load_plugin(): Loaded plugin Linktop modem-manager[6245]: <info> [1316615687.386162] [mm-manager.c:120] load_plugin(): Loaded plugin Longcheer modem-manager[6245]: <info> [1316615687.386582] [mm-manager.c:120] load_plugin(): Loaded plugin X22X modem-manager[6245]: <info> [1316615687.387050] [mm-manager.c:120] load_plugin(): Loaded plugin Novatel modem-manager[6245]: <info> [1316615687.387468] [mm-manager.c:120] load_plugin(): Loaded plugin Generic modem-manager[6245]: <info> [1316615687.387904] [mm-manager.c:120] load_plugin(): Loaded plugin Samsung modem-manager[6245]: <info> [1316615687.388325] [mm-manager.c:120] load_plugin(): Loaded plugin Nokia modem-manager[6245]: <info> [1316615687.388748] [mm-manager.c:120] load_plugin(): Loaded plugin SimTech modem-manager[6245]: <info> [1316615687.389193] [mm-manager.c:120] load_plugin(): Loaded plugin Ericsson MBM modem-manager[6245]: <info> [1316615687.389637] [mm-manager.c:120] load_plugin(): Loaded plugin ZTE modem-manager[6245]: <info> [1316615687.390064] [mm-manager.c:120] load_plugin(): Loaded plugin Wavecom modem-manager[6245]: <info> [1316615687.390492] [mm-manager.c:120] load_plugin(): Loaded plugin Sierra modem-manager[6245]: <info> [1316615687.390977] [mm-manager.c:120] load_plugin(): Loaded plugin Huawei modem-manager[6245]: <info> [1316615687.391404] [mm-manager.c:120] load_plugin(): Loaded plugin AnyData modem-manager[6245]: <debug> [1316615687.397584] [mm-manager.c:809] device_added(): (tty/ttyS0): port's parent platform driver is not whitelisted modem-manager[6245]: <debug> [1316615687.397994] [mm-manager.c:809] device_added(): (tty/ttyS1): port's parent platform driver is not whitelisted modem-manager[6245]: <debug> [1316615687.398337] [mm-manager.c:809] device_added(): (tty/ttyS2): port's parent platform driver is not whitelisted modem-manager[6245]: <debug> [1316615687.398667] [mm-manager.c:809] device_added(): (tty/ttyS3): port's parent platform driver is not whitelisted modem-manager[6245]: <info> [1316615687.404036] [mm-serial-port.c:741] mm_serial_port_open(): (ttyUSB1) opening serial port... modem-manager[6245]: <debug> [1316615687.404123] [mm-serial-port.c:810] mm_serial_port_open(): (ttyUSB1) device open count is 1 (open) modem-manager[6245]: <debug> [1316615687.404141] [mm-plugin-base.c:850] try_open(): (ttyUSB1): probe requested by plugin 'Gobi' modem-manager[6245]: <debug> [1316615687.404225] [mm-at-serial-port.c:298] debug_log(): (ttyUSB1): <-- '<CR><LF>+PACSP0<CR><LF>' modem-manager[6245]: <debug> [1316615687.504556] [mm-at-serial-port.c:298] debug_log(): (ttyUSB1): --> 'AT+GCAP<CR>' modem-manager[6245]: <debug> [1316615688.204741] [mm-at-serial-port.c:298] debug_log(): (ttyUSB1): <-- 'AT+GCAP' modem-manager[6245]: <debug> [1316615688.206753] [mm-at-serial-port.c:298] debug_log(): (ttyUSB1): <-- '<CR>' modem-manager[6245]: <debug> [1316615688.207998] [mm-at-serial-port.c:298] debug_log(): (ttyUSB1): <-- '<CR><LF>+GCAP: +CGSM,+DS,+ES<CR><LF><CR><LF>OK<CR><LF>' modem-manager[6245]: <debug> [1316615688.208129] [mm-serial-port.c:844] mm_serial_port_close(): (ttyUSB1) device open count is 0 (close) modem-manager[6245]: <info> [1316615688.208149] [mm-serial-port.c:859] mm_serial_port_close(): (ttyUSB1) closing serial port... modem-manager[6245]: <info> [1316615688.208691] [mm-serial-port.c:880] mm_serial_port_close(): (ttyUSB1) serial port closed modem-manager[6245]: <debug> [1316615688.215410] [mm-manager.c:491] try_supports_port(): (Huawei): (ttyUSB1) deferring support check modem-manager[6245]: <debug> [1316615691.218642] [mm-manager.c:457] supports_defer_timeout(): (ttyUSB1): re-checking support... modem-manager[6245]: <debug> [1316615691.219568] [mm-manager.c:491] try_supports_port(): (Huawei): (ttyUSB1) deferring support check after that I only get the re-checking support and deffering support check messages. lsusb -v output: Bus 001 Device 019: ID 12d1:14f1 Huawei Technologies Co., Ltd.

Gobi modems should be driven by the Gobi plugin, at least for now; so I've pushed a fix to ModemManager that will make the Huawei plugin ignore these devices. 6e0e46e51e9b022577db6adeb986d3241da9bd4d (master) b0ab973d074a13c00f74a659aa11811529a3276f (0.5.x)
