If these stages have not happened, ensure the driver is loaded, check the output of lsmod. Second, check that the driver has bound to the device, after making a connection to the USB, the following message should be present in dmesg, “CP210x converter detected”, and “CP210x converter now attached to…”

There should be a line saying something similar to “cp210x.c: Silicon Labs CP2101/CP2102/CP2103 RS232 serial adaptor driver…”

Note: The driver version numbers for the 2.4 and 2.6 development branches are not related because the two drivers are maintained separately. Using cp210x devices with older kernels, 2.4 series and 2.6 <2.6.12, is possible by applying the appropriate patch to the kernel source. The Linux kernel can be downloaded in source form from. CP210x based devices will be detected automatically, the kernel module will automatically load and the device node /dev/ttyUSBx will be created. Almost all Linux distributions have this as part of the default installation. The CP210x driver is distributed with the Linux kernels newer than 2.6.12.

TIOCMGET/TIOCMSET ioctls enable flow control lines to be fully programmed.

The open source driver supports the majority of the features of the CP210x devices, and should in theory be compatible with the basic functionality of the CP2103. With no data-sheets available, this driver had to be produced by tediously analysing the protocol used by the windows drivers. This feedback has only reinforced my belief that using an open standard protocol for this type of device would have made it more appealing to many product designers. Well, it’s out in the open now!Īfter writing the first version of the open source driver, I received feedback from numerous companies, some with names we all recognise. For some reason the manufacturers try to keep the protocol used for configuring this device secret. The cable was advertised as having Linux support however this was far from the case since the only Linux driver that was provided was in binary form, and for a specific Red Hat Linux kernel. The project began in December 2004, after purchasing a CP2101 based USB to RS232 converter cable. In the majority of cases, no further action is required to use CP210x based devices. The CP210x driver is now distributed with 2.6 series kernels, and should be compiled and part of the default installation for most modern Linux distributions. The driver discussed here is 100% open source, and is licensed under the terms of the GNU General Public License. This is the project page for the Linux driver for CP2101, CP2102 and CP2103 based USB to serial bridges.
