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! Michael J. Kidd
