sata to usb 3.0 adapter

Hi, i have laptop with usb 3.0 ports and usb 2.0 ports, recently i bought sata to usb 3.0 adapter and when it is connected to usb 3.0 port lsusb command is showing that idProduct is "VL711 SATA 6Gb/s bridge" and it works, but when i connect it to usb 2.0 it will not be detected, there is no info in dmesg about connecting anything. does this mean that this adapter works only on usb 3.0? arent usb backward compatible? can i do something to make it works in usb 2.0, maybe i need some kernel module or change some options? my kernel version is 5.15.18-1-lts. thanks for help.

Re: sata to usb 3.0 adapter

i bought sata to usb 3.0 adapter ... does this mean that this adapter works only on usb 3.0?

Yes.

arent usb backward compatible?

No - not in that direction.  Anything that requires usb2 will work on a usb3 port, but if you have a peripheral that explicitly requires usb3 then you need to plug it in to the usb3 port.

can i do something to make it works in usb 2.0, maybe i need some kernel module or change some options?

No.  Software can't change the number of wires connected at the port.

Arguably, any good 3.0 device should do *something* on a 2.0 port, even if it can't work at full capacity.  But if a device really requires 3.0 features, then there's no way around that.

Re: sata to usb 3.0 adapter

Hi,
I have the opposite problem with the same adapter, or based on the same chipset. It's a short cable, USB-C on one side, SATA connector for 2.5" drives on the other. When I plug it into USB-C on my laptop, I hear the drive spin up and both LEDs on the sata connector light up (labeled access and power), but dmesg shows this:

[4293661.645608] usb usb2-port1: attempt power cycle
[4293666.035435] usb usb2-port1: Cannot enable. Maybe the USB cable is bad?

lsusb doesn't see it at all.

However, if I connect it via a reducer to the USB-A connector of the same laptop (with the latest Arch), it starts up and works (both LEDs light up the same way like before).

dmesg:
[4294927.708868] usb 1-3: new high-speed USB device number 7 using xhci_hcd
[4294927.856517] usb 1-3: New USB device found, idVendor=2109, idProduct=0711, bcdDevice= 1.44

Re: sata to usb 3.0 adapter

USB-A and USB-C are port connectors. USB 2.0 and USB 3.0 are protocols.

What type of laptop is this?

Cheers,
