Output from "/var/log/messages", driver is "cdc_acm":Ĭode : T12:32:55.433571-05:00 CuBox-HQ kernel: usb 2-1.4: new full-speed USB device number 7 using ci_hdrc So you'd think they would work pretty much the same. You would see the exact same thing when connecting each modem.

Even if you watch /var/log/messages when connecting each modem the both report the exact same Serial Number and Manufacturer. The strange thing is both of these modems look the EXACT same, other then the physical color of the modems they are the same. On this modem the CID worked perfectly with mgetty, so we decided to use this one since the CID was of the upmost importance. But, since the PC will except calls based on the CID, this part was not exceptable so we tried this I'm pretty sure it's an mgetty thing since theĮxternal CID worked in Putty (*for linux and Windows). Locking up, but there was an issue with External Caller-ID NOT working when the CID came from the TelCO. This modem worked MUCH better in terms of never really The 1st Modem was a Zoom USB Modem Model 3095. This is the 2nd USB Modem I've tried using. On the other end (*during testing) just to see what happens and the modem completely locks up and the only way to get it back is to either reboot the PC or

There has been a few times where I hang up randomly Most of the time it will reset correctly when an unexpected hang up occurs, but not everytime. But in certain cases the modem seems to hang and it stops excepting AT Commands and becomse completely unresponsize at certain

You shouldn't need to reset the USB port, the modem software (driver should take care of it. So it seems like it's recognizing the modem, but when I physically unplug and re-plug back in the modem I get more messages printed then what you see above.

The C code at the end of the post seems to "shutdown" that USB port, but it doesn't seem to re-rigester the device. But I'm not sure if that command will help my cause.? If not does anyone know of any other soultion that I might try? I saw there was a command called "udevadm", and with that your supposed to be able toĬontrol udev and devices, I believe. Not sure if something is incorrect in the code below seeing that I have only limited knowledge of C, I was wondering if someone elswe could tell.? So after searching around a bit online I found this C program that is supposed to do exactly what I was trying to do, but it doesn't seem to be working properly. PC will be in a remote location where I won't have access to it physically, I was hoping to find another solution. I'd rather not reboot if that's possible, and since this So I have been running into an issue with a USB Modem where if someone ends their dialin connection abruptly from the other side the modem gets stuckĪnd I found that the only way to fix it is to either unplug the USB Modem and plug it back in, or just reboot.
