Review on Rosewill RCR-IC001 USB 2.0 3.5-Inch Internal Card Reader & USB Port with Extra Silver Face Plate (RCR-IC001) by Steve Atchley

This *is* a powered USB hub and currently offers much better performance than Kingwin front bay USB hubs. I bought this to replace the USB/SATA ports in the OEM top front case. Somehow one of the case's USB ports melted from having the USB stick plugged in all night. Two USB/SATA ports and electronics are likely to have compromised integrity now. After connecting the Rosewill device, all USB ports seem to work fine with USB2/USB3 flash drives along with the keyboard attached. I haven't checked the port speed ratings, but it is believed that they are probably operating at the appropriate USB2/USB3 speeds. I haven't tested the SATA port either. Cons 1) Testing MicroSD ports can't read MicroSD flash card with either MicroSD flash slot or larger SD adapter flash slot in Linux.

This MicroSD card works great with a USB adapter.
