USB2 to USB3 adaptor??
I only have USB 2 ports on my Optiplex.
So a dummy question, please.....
Does this device actually upgrade to USB 3 without adding a PCI card?.

Apologies, I didn't read all the Q& A's as too many

Which model Dell do you want to add USB3 to and why do you think you need that?

RS 232 is very old and not used most places. I havent used it since 1965. USB2 is fine for most things.RS-232, Recommended Standard 232 is a standard originally introduced in 1960 for serial communication transmission of data. RS 232 Revision C was issued in a document dated August 1969. Revision D was issued in 1986. The current standard is TIA 232 F

RS-422, also known as TIA/EIA-422, is a technical standard originated by the Electronic Industries Alliance that specifies electrical characteristics of a digital signaling circuit. It was intended to replace the older RS-232C standard with a standard that offered much higher speed, better immunity from noise, and longer cable lengths.
USB 2.0 was released in April 2000, adding a higher maximum signaling rate of 480 Mbit/s (60 MB/s) named High Speed or High Bandwidth, in addition to the USB 1.x Full Speed signaling rate of 12 Mbit/s.
USB 3.0 (also known as Super Speed USB) has a maximum bandwidth rate of 5 gbps (gigabits per second). That translates to 640 MBps (megabytes per second)—ten times faster than USB 2.0 (aka Hi-Speed USB). By comparison, Intel’s Thunderbolt 2 technology allows theoretical data-transfer speeds of up to 10 gbps.

@foxleybob, I used a pcie card in my machine to add 4 usb3 ports. It cost less than $10 with shipping, but since I bought it from a chinese ebay seller, it took about a month to get it.
I don't know any other way to get USB 3, if the motherboard doesn't have it.
@speedstep Nobody needs usb 3, or even usb 2, but it's a wee bit faster, so some of us really like that, though we don't really need it. RS-232 works just as well, but slower.
EDIT: One other thing Bob ... even with a usb 3 card, you'll still have to use the old usb 2 ports to boot from a flash drive. This is because there isn't a boot rom on the pcie card, and your dell bios doesn't know about the usb 3 ports on the pcie card.

Your point that we don't need any of this is well taken. I used to know some old timer ham radio operators that could send morse code at 60 wpm, using a straight transmitter key, no fancy electronic keyer with iambic paddles. Those guys are probably silent keys now.
Some of us are just lazy and impatient. We like something faster than usb 1.1 or 2.0, though we certainly don't NEED it. RS 232 @300 baud still works fine.
