Note: The USBxCH system software supports both
USB4CH
and USB8CH
including drivers, apps, and utilities. Note: Linux software *MUST* match the bit size of your machine. Linux 32 bit available by request. Note: Linux software also works on many other Ubuntu revs and distros such as Debian. Note: BeagleBone Black single board computer software compiled on Linux 3.8.13-bone47 also works on 4.4.9-ti-r25. Note: If you are upgrading from a pre-2011 version, please remove old custom kernel drivers first. |
