Hello, thanks for having this forum. I recently bought a Rosewill front panel card reader model RDCR-11004. As I am installing it I find a USB3 cable with a blue connector having 19 holes. The problem is that there is no mating connector on my motherboard. There are 2 USB3 connectors on the back panel but no where to plug in the cord. Is there a workaround for this dilemma? So far it looks like I don't get to use the USB3 connectors on the front panel. Thanks for any suggestions.

Welcome to Motherboards org.
Unfortunately, your board does not have the dedicated 20-pin USB dual port. Not an industry-wide standard yet.
But there are adapters so you can connect to a 10-pin USB port, and use the 20-pin device cable.
New Egg has them..

Link to manual..

Just would have to limit the USB port and reader combined use so as not to overload the USB power source.
Maximum current is 1/2 amp or 500 ma at +5 volts per port.
An alternative would be to get two of the adapters and splice a lot of wires, to have four USB port sources. But too much work!

Hi Karlsweldt, thanks. That sounds like a good idea, but while shopping on eBay, I found a PCI-E card that has two USB3.0 ports, a SATA port and a 20 pin connector. I think that would be better even though it costs a bit more and it would have a lot longer shipping time since it comes from Asia. I'm not in a rush. I don't have any USB3.0 connectors on my board, so I would have to plug the cable into a USB2.0 connector which I believe would compromise the USB3.0 data flow. I happen to have a spare PCI-E slot on my board. Here is a picture of it.

What do you think?

I appreciate your help, Jim

Should be no real noted difference between USB 2.0 and USB 3.0 performance, with most devices. Only if the device is a high-speed data type. USB 2.0 has a 480 Mb/s data rate, USB 3.0 has a 5 Gb/s data rate. A newer USB 3.1 has a 10Gb/s rate. All are maximum ratings. The USB standards mandate that newer versions are backward compatible.. but not forward compatible. https://en.wikipedia.org/wiki/USB

Thanks Karlsweldt, yeah you are right. I would probably never notice the difference, but I'm kind of nutty about such matters. Every time I plug my phone into a USB2.0 for backup, I get a warning that it would go much faster if I would use a USB3. It gives me an inferiority complex. :-| Thanks again, Jim

Likely the "latest and greatest" fever is spreading to too many products, as we crave instant gratification.
But there are still countless devices that don't go "all out" for speed and pleasure. Yet they do perform admirably.
All good things in their own time.

heh heh heh, you are so right. And I'm the chief victim of that phenomenon. Oh well...

I don't find a place to mark this topic as [Resolved] Is there a way?

If the problem is indeed resolved, great news.
This thread will remain open for anyone else to view.
Perhaps their problem is similar, and the fix is also.

That's great Karlsweldt!!! I have ordered the card. I'll let you know how it works out. Another thing that will be better is the current load you mentioned. Bye, Jim
