Version 1.0.0.101 - June 16, 2010 ---------------------------------------- 1. Problem: CQ48270 - Fails to continue data transfer after system resume from S1, S3, & S4. Cause: Bus change notification issued on both stopping the adapter and restarting it. SRBs submitted during host controller and flash memory card initialization are rejected. Change: Omit the bus change notifications if start and stop adapter processing is in progress. Return a busy indication to SRBs during initialization. Impact: Notes: 2.

Cause: Cards unstable at higher speeds and bus widths. Change: Run all MMC cards at lower speeds and 1-bit data bus width. Impact: Notes: 2. Problem: CQ47211 - Microsoft inbox driver cannot detect some MMC cards. Cause: Improper access to specific MMC cards. Change: Added MMC support to Broadcom SD driver. Impact: Some cards will require Broadcom driver and not inbox driver. Notes: 3. Problem: CQ48192 - Unable to detect SD card after ungraceful remove and re-insert. Cause: Removal of "Software Reset for All" will not allows host controller to be reset to a known state. Change: Allow "Software Reset for All" when media is present.
