ACPI not setting up I/O Memory mappings for USB and PCMCIA controllers
on Averatec C3500 Laptop.. Can anyone help with this? Please...
Michael J. Kidd
Hello all,
I have an Averatec C3500 Convertible Tablet PC. With the initial bios
version that ships with the unit, USB and PCMCIA both work fine in
linux. However, there is a terrible keyboard lag and dropped keys.
The follow-on bios revisions fixed the keyboard issues, but caused USB
and PCMCIA to both stop working. Note: All devices continue to
operate fine in Windows. I'm posting this here in hopes that someone
will take interest in this issue ( there are several others trying to
use linux on these laptops. ) I've captured dmesg output after
enabling CONFIG_USB_DEBUG and CONFIG_PCMCIA_DEBUG in the kernel
config, and the output from lspci -vvxxx, as well as the DSDT output
from both the original BIOS ( USB working / Keyboard not ) and the
latest BIOS revision ( USB Not working / Keyboard works great ).
The link for all this captured data is:
http://www.linuxkidd.com/c3500 I've detailed the machine hardware,
running kernel, etc.. as well as linked to all the above described
captures.
After posting the above request to the linux-usb list, Alan Stern
responded with:
----------------------------------------------------------------------
According to the log, the I/O memory mappings for the USB and PCMCIA
controllers aren't getting set up. It's not a USB or PCMCIA issue at all;
you should ask for help on the PCI and ACPI mailing lists.
----------------------------------------------------------------------
So, here I am...
If there's anything else I can provide to assist in troubleshooting,
Please ask! I'd really like to get this working.
Thanks in advance for any help!
