I need some kind of cable or adapter that lets me connect any USB device (eg. Flash drive, printer, WiFi) through a SATA interface. I checked eBay but all I could find were SATA to USB adapters. I need one that goes the other way if it's possible. If these adapters or cables do exist, where can I find one? Thanks!
I need this adapter because I have an old mini itx motherboard which only has 2 USB 1.1 ports which are not suitable for most of my usb needs, plus they're being used for the mouse and keyboard. I have a PCI card with 4 SATA ports and one is being used for a secondary HDD. That leaves 3 spare SATA ports which I'd like to use for other USB devices if possible because I have no spare/compatible usb 2.0 or higher ports.
There is no way to plug a USB device into a sata port.
You could look at a USB2.0 PCI card. They are around 10-20 on newegg.com
If you only have 1 pci port you can try to get a Sata - USB2 combo PCI card. 1 card has both usb and sata ports. Those are around 40 on newegg.
