This could be related to a change that was incorrectly made to the DTR/RTS handling. This change has later been reverted (commit 677aeafe19e88c282af74564048243ccabb1c590 upstream). Could you see if 2.6.37-rc2 works as it should? The revert will also be part of 2.6.36.1 (and 2.6.35.9) soon to be released. > The device is correctly identified and /dev/ttyUSB0 and /dev/ttyUSB1 are > created, but at least /dev/ttyUSB1 does not transmit or receive data. > I'm running Kernel 2.6.32-25 on Ubuntu 10.04 but I could also verify this > problem on Kernel 2.6.35-7.
