#USB CDC ACM DRIVER LINUX DRIVERS#
I think that uhci_hcd is for hard drivers right? Jun 16 11:18:15 ubuntu kernel: usb 1-1: configuration #1 chosen from 1 like on boot it seen it right as cdc-acm.c but then when I unplugged it and plugged it back in it thinks it's a uhci_hcd. Jun 16 11:18:15 ubuntu kernel: usb 1-1: new full speed USB device using uhci_hcd and address 3 Jun 16 11:18:04 ubuntu kernel: usb 1-1: USB disconnect, address 2

Jun 16 10:51:53 ubuntu kernel: /build/buildd/linux-2.6.24/drivers/usb/class/cdc-acm.c: v0.25:USB Abstract Control Model driver for USB modems and ISDN adapters Jun 16 10:51:53 ubuntu kernel: usbcore: registered new interface driver cdc_acm Jun 16 06:47:33 ubuntu kernel: lo: Disabled Privacy Extensions I booted with the USB modem plugged in and did the command sudo modprobe cdc_acm then unplugged the USB modem and plugged it back in. On another PC I booted Ubuntu live desktop 8.04 same as I have only the server type.
Jun 16 04:17:05 small kernel: usb 4-4: configuration #2 chosen from 1 to me that it's using ehci_hcd and not cdc-acm like it should. Jun 16 04:17:05 small kernel: usb 4-4: new high speed USB device using ehci_hcd and address 4 Jun 16 04:16:57 small kernel: usb 4-4: USB disconnect, address 2 It's been a long time from posting this and no one can help.Īfter I rebooted and unplugged the USB modem and plugged it back in and did a tail /var/log/messages command I get this back now. I think that's the one RS232 port on the mini-itx motherboard I am running it on. The 2 last ones are when I did minicom as /dev/ttyS1 but it comes back saying: Jun 15 10:37:38 small kernel: ttyS1: LSR safety check engaged! Jun 15 10:37:06 small kernel: ttyS1: LSR safety check engaged!

Jun 15 10:10:29 small kernel: tun: Universal TUN/TAP device driver, 1.6 Jun 15 10:09:48 small kernel: device eth0 entered promiscuous mode If I do a tail /var/log/messages after I reboot is shows this: Minicom: cannot open /dev/ttyACM0: No such file or directory Looked on the web my USB modem should be on /dev/ttyACM0 but minicom says: I went in minicom and did the port for /dev/ttyS1 but I don't think that's the USB modem. I think that's because all the things I have done to get this USB modem to work. I could only say yes or no and I said yes and it booted up then. Then it said something like change the network. It did not come back on a reboot till I hooked a screen to it. I rebooted my Ubuntu server because I did so many things to get the USB modem to work.

You do not need to install any drivers off the USRobotics installation CD-ROM.Ĭan any one tell me what to do by what this quoted text says? Installation of the modem under these kernels is fully automatic provided your kernel has the Plug and Play module enabled (default). You need a USB modem driver (CDC ACM) compiled into a Linux kernel 2.4.20 or higher or as a loadable module for your kernel. What /dev would this be on? Or do I need to install some driver? lsmod command shows this cdc_acm in it like this: When I do a modprobe cdc_acm command it looks like it does nothing. Predictive diagnostics for card in bus 001:
(Lucent) I know because if I unplug the it from the USB and do lsusb again it's not there.
