NAK, compiles and loads fine but, i have no data flow to/from my device.
Windows and Mac OS, work fine and Kernels 2.6.15(or maybee earlier)
through 2.6.30 worked fine up until 9a68e39d4a.
What application are you using, where does it block and what termios
settings are in use by the app ?
Minicom and cutecom. 8 Databits No parity 1 stop bit. 19200 baud, no
flow control, but the devices needs DTR and CTS at the correct levels to
send data.
as soon as i do stty -a the device comes alive as DTR and CTS get set
at the correct levels.
stty -a < /dev/ttyUSB0
speed 19200 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z;
rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 5;
