USB Ports - HP Pavilion Desktop TP01-2255t

[Tex98]

Question about USB Ports on my HP Pavilion Desktop TP01-2255t (Product #20W69AA#ABA).  There are three USB 3.1 Gen 1 ports on the back.  May I use USB 3.1 Gen 2 in these ports, or am I restrict to Gen 1?  Thanks!

You can use gen 2 on those ports but it will only run at gen 1 speed

USB 3.1 Gen 1 vs USB 3.1 Gen 2

The difference between USB 3.1 Gen 1 and USB 3.1 Gen 2 is only in terms of speed. USB 3.1 Gen 1 supports speeds of up to 5Gbit/s while USB 3.1 Gen 2 supports speeds of up to 10Gbit/s. The USB-IF intended to use a set of different names to call the USB 3.1 Gen 1 and USB 3.1 Gen 2 that would’ve made it better strictly for marketing purposes. They wanted to name USB 3.1 Gen 1 and Gen 2 "SuperSpeed USB" and "SuperSpeed USB+" respectively, but the industry never caught on. Often, OEMs will add the speeds of 5Gbps or 10Gbps to their spec tables in order to differentiate between the two USB standards. The rest of the industry just refers to them as "USB 3.1 Gen 1" or "USB 3.1 Gen 2."

According to the following spec you have 3.1 gen 2 ports

That picture you posted is misleading as it indicates all are 3.1 gen 1

 However the superspeed "SS" are gen2.  I have not read anything about Gen3, not sure where HP got that unless they invented it recently

Where did you obtain the picture you posted?  Can you provide the URL link to the website?  The notations scribed under the 4 ports indicate they are all super speed which conflict with the product spec.  Something is wrong as your picture is of the back and that spec for the 2255t  indicates the front
