Public bug reported:
USB devices attached via a USB-PCMCIA Adaptor are not recognised at boot
time. After a "cold start", once the system has booted up, I must
manually remove and insert those devices in order to make the system
recognise them. After a "warm restart", some of them are recognised,
some not (see below for more details about which ones).
My system is a HP-Compaq laptop (NC8000 family) with two USB2.0 ports
and a pcmcia expansion slot, in which I have a PCMCIA-USB
adapter/hub/controller (don't know the correct term :) that expands the
laptop connection with two new USB ports). Attached to each port are:
USB1 = Pinnacle dual dvb-tv tuner (recognised without problem)
USB2 = Arduino board (works with ftdi_sio as a serial port connected via USB)
PCMCIA USB1 = Pinnacle dvb-tuner (problems at cold boot)
PCMCIA USB2 = IOMega external hard drive 500GB (problems at cold/warm boot)
Devices attached directly to laptop's USB ports work without any
problem. For devices attached via USB additional ports (via PCMCIA),
there are two scenarios:
A) Cool booting (laptop switched off -> laptop switched on):
- The Hauppauge dvb-tv is not recognised until I manually unplug and plug it
back again. At that poit, it is recognised and initialised, and everything
works ok regarding this device
- The iomega storage is recognised but not mounted (it has an entry in
/etc/fstab) and I must manually mount it
B) Warm reboot (laptop reboot without unplugging)
- The hauppauge dvb-tv is recognised and works properly (no problem here)
- The iomega storage is recognised but not mounted (same that in the (a)
scenario)
Some days ago, my first configuration was different, and the Arduino
board was connected to the PCMCIA adapter, which was causing also
problems: kind of unresponiveness when reading via /dev/ttyUSB from the
board, after plugging it into a "native" USB port, the problems
dissapeared)
I don't know exactly the package where the problem is, but probably
something related to udev?
