devices attached to PCCard-USB adapter not recognized at boot time

Bug #235672 reported by JoseO on 2008-05-29

Bug Description

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?

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at . I have classified this bug as a bug in linux which is the kernel from Hardy Heron. In the event that this is not a kernel bug the kernel developers will be better able to determine the correct package.

There hasn't been any recent activity in this bug report and we were wondering if this is still an issue? The Ubuntu kernel team is actively working on the upcoming Intrepid Ibex 8.10 release. If you could please test the latest Alpha release for Intrepid it would be much appreciated - . Please let us know your results. If the issue still exists, please also provide the appropriate debugging information as outlined at . Thanks in advance.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.


2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Problem seems to exist in 2.6.27 too. Does not detect USB hard disk, but detected mouse on bootup, both attached to the same USB extension port. Seems to be endemic to hard disks somehow, Speakers & Input devices are always detected on bootup but hard disks needs to be restarted.

Problem exists even if connected directly to notebook, not specific to the USB expansion dock.
