 Posted: Mon Jun 05, 2006 5:50 pm Post subject: PCMCIA does not receive power |
 |
|
I own an IBM t43p, and a KPC650 pcmcia card.
I've included a list of commands below to show the status of my system, as well as a few things I've tried. I've also thrown a couple of printk's into drivers/pci/probe.c and discovered that when the pcmcia card is inserted, pci_bus_read_config_dword returns something other than the vendor/device id for the card, and pci_bus_read_config_word for the vendor/device return 0xffff in all cases.
I have never managed to give power to the card. The light stays off in all cases.
Any help would be greatly appreciated.
thank you,
Harrison
