PDA serial/USB cable busted after hardware/software upgrade?
hi debian,
I was until recently running debian sid on a middle-aged amd k7
system; after the motherboard fried, I upgraded to a very fast new
system (amd X2 3800+, A8N-SLI motherboard and installed ubuntu Dapper
and debian etch on a new disk. The old system is still around on an
old disk, but hard to work with b/c I haven't reconfigured x etc.
On my old system, my PDA worked fine -- it's a Palm V, which I ocnnect
through the serial cradle that came with it a million years ago. I
also have a usb-to-serial connector for it, which in the past has also
worked *pretty* well via the kl5105kb kernel module. Now, though, the
PDA doesn't work at all. At first it seemed to be a problem with
evolution and gnome-pilot, and I *was* briefly able to access the
palm's info through pilot-link (pilot-xfer -p /dev/ttyUSB0 -l, IIRC).
Now even that won't work, and unscrewing the serial-to-usb adaptor &
plugging in directly to the serial port has no effect either
I'm a little concerned that the cradle itself is messed up somehow,
partly becuase of some strange stuff in dmesg.
serial:
serial port seems to be recognized just fine by the kernel, early on
in the boot process:
[ 85.877857] Serial: 8250/16550 driver $Revision: 1.90 $ 48 ports,
IRQ sharing enabled
[ 85.877964] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 85.879621] 00:07: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 85.880057] RAMDISK driver initialized: 16 RAM disks of 65536K size
1024 blocksize
however, there's no traffic on /dev/ttyS0 (cat /dev/ttyS0, and then
pressing hotsync button, gives no output) while ttyS1 seems
fundamentally messed up:
$ cat /dev/ttyS1
cat: /dev/ttyS1: Input/output error
USB:
If I connect my usb/serial converter, then I have similar problems.
Dmesg shows it being recognized, and at FIRST binds to /dev/ttyUSB0
and /dev/ttyUSB1, but if I unplug & replug, I only get /dev/ttyUSB0.

---------------------
I of course know nothing about what this might mean. In any case I'd
love some advice on howto diagnose these
+issues further! the evolution/palm combination has been crucial for
me. thanks,
matt
