Hi guys.
I saw a certain news.
This news is errata of "Intel P55 Express" Chip set.
In the group of either mentioned above an USB1.1 full speed (12Mbps) synchronization transfer device (ex: Audio system) and an USB1.1 async transfer device (ex: keyboard and mouse) coexist, that cannot transfer to a synchronization transfer device normally.
I had a conversation with a customer about this.
The customer got a good result with the following device.

best regards,
