Do the two modinfo commands give any results? Does the added output from the edited question help verify the problem? The PI uses udev though. I don’t know the details. The CPx driver is distributed with the Linux kernels newer than 2. Amber 18 1 7.

Brian is correct in that ther version of our driver with GPIO support has not been included in the Linux kernel due to some conflict with system level IO stuff I am similarly lacking in expertise on the details ljnux all of this. Since the flow control lines were not touched, the early version of the driver left them in the wrong state. Munir Nassar provided further useful informationin the form of USB packet logs, and very kindly sent me a cable which had all of the flow control lines connected.
CP210x USB to UART Bridge VCP Drivers
Whether or not these modules will allow a Wine program to access the device is unknown. Project History The CPx driver is now distributed with 2.
It had very basic support for opening the device, setting the baud rate. Email Required, but never shown. The driver version numbers for the 2. Karl Hiramoto, a developer with access to a CP evaluation kit, provided excellent information by testing development versions of the driver, and was able to establish the correct bit mappings of all of the flow control lines. Matthias Frei 6 1 4. Is this supposed to show up as a ttyUSB or other tty?
I don’t want to ruin stuff by randomly typing code into the terminal so I’d appreciate some guidance! I added the modinfo to the original question yesterday after I commented. Additionally, the following knowledge base may provide a bit more information about the differences in these linux CPx drivers:.
Installing CPx Driver? – Ask Ubuntu
Is there any particular reason why no patch was sent to the linux kernel maintainers to get the gpio functionality of the CPx devices integrated? I’m sorry, I totally should have included this in the original, I’m running Sign up using Email and Password.
Now, the download has four files, the release notes abovecpx. Remember that sudo echo Replied Sep 153: I have a little Python script running on a Windows machine that is able to talk to the very device just fine If those two files don’t exist, then you’ll need to compile your source code yourself.

Please remember to accept my answer cp21103 it was helpful. We have plans to release a library module that will allow CPx GPIO manipulation in Linux that will work in parallel with the built-in kernel driver. The Linux kernel can be downloaded in source form from https: I have a Freescale embedded device, mx23, that uses mdev instead of udev and the procedure is a bit different.
We do not currently have a time estimate for this library feature, though it is planned for sometime in the future. The CPx driver is distributed with the Linux kernels newer than linxu.
Replied Sep 159: Since I’m fairly new to Linux and I need that thing running, I’d be grateful for suggestions.
