剛剛看過安國相關chip的介紹,有支援SD1.1規格的只有
AU6367
AU6366
AU6375
AU6333
用這些chip的才有支持高速SD,
其他型號都沒有~

你可能沒注意到AU6331那頁(
http://www.alcormicro.com/products_...in_id=5&p_id=42)有這一段敘述"AU6331 is an USB2.0 transmission controller, which is designed as an interface bridge between USB host and SD/MS compatible flash card, such as SD,
HS-SD, MMC, HS-MMC, RS-MMC, MMCmicro, MS, MS Pro and MS Duo…etc."
其中HS-SD應該就是SD1.1的規格
SG365A的讀卡機就是用AU6331的晶片..
附上一張創見 1g 80x的sd卡的測試結果
(測試平台是P4賽揚 1.7g...)
