JMicron SDIO drivers problems

NTDEV
1

I am developing an SDIO driver for an HP EliteBook 8460w running Windows
7 64-bit. It comes with the Jmicron PCIe SD Host Controller and Jmicron
PCIe SD/MMC Host Controller under the Memory Technology Driver in Device
Manager. I am having problems with these Jmicron drivers, will
appreciate any pointers on how to get them to cooperate.

  1. When I insert my device into the SD port, the Jmicron drivers cut off
    its power after exchanging a few commands. In contrast, a Windows XP
    machine with the SDA Standard Compliant SD Host Controller keeps my card
    powered and prompts me for a driver, at which point I can successfully
    load the mars sample driver.

  2. If I install mars while the Jmicron drivers are present, I get error

  3. If I uninstall and remove the Jmicron drivers, mars installs fine
    and works. I then see SDA Standard Compliant SD Host Controller in
    Device Manager.

For now, I have been working with these Jmicrons uninstalled. How do I
go about getting them to work?

Thanks
Rachel

I don’t think there’s any way for us to answer this question. You’ll
have to talk to Jmicron.
