PSoC 4 Pioneer Board - USB-UART Bridge - Debian/Ubuntu/Mint Linux
I have my PSoC 4 Pioneer Board wired to bring the PSoC Rx/Tx lines over to the the PSoC 5LP in an attempt to use the PSoC 5 LP as a USB-UART Bridge. This, in fact, works as expected with PuTTY and MS Windows.
However, plugging that cable into a machine with a recent version of Linux, does not yield the same success.
The USB core code is able to query the Cypress KitProg, but, cdc_acm fails to probe the device.
