hdc2450 on linux with usb

9 years 5 months ago #29525505 by john_jsb
I can\'t seem to get linux connected through usb. what usb chip set is used in the controller? I could use the serial on the db25 but i don\'t have a real serial port available. Which leaves a usb converter as my last resort. I\'ve read this post:
dev.roboteq.com/dev1/online-forum/genera...mmunication#29525335
but i\'m not seeing /dev/ttyACM0

We have no direct experience connecting the controller to a Linux machine and have it recognized as a serial port. Attached is the windows driver for it. The .inf file may contain the information you need to configure your linux driver.

John,

what does your dmesg say when you plug it in? Here is mine:
[2389570.816748] usb 3-1: new full speed USB device using uhci_hcd and address 4
[2389571.007888] cdc_acm 3-1:1.0: This device cannot do calls on its own. It is not a modem.
[2389571.007913] cdc_acm 3-1:1.0: ttyACM0: USB ACM device
[2389571.010396] usbcore: registered new interface driver cdc_acm
[2389571.010397] cdc_acm: v0.26:USB Abstract Control Model driver for USB modems and ISDN adapters

Obviously the power and USB light should both be active on the side of the controller, if the power is and the USB isn\'t, it\'s not connected.

The linux download they offer on the site does not work at all, i re-wrote it to work, but ditched it after I realised just using the serial api was easier.

What distribution are you using? What kernel version are you using?

Type \'dmesg -c\' before plugging in the controller, then next time you type \'dmesg\' you\'ll see just the new messages from plugging it in, post those back here.

`uname -a` will get you the kernel version.
