LACIE Rugged Triple USB 3 recognised as USB 2.0 only - ideas?
Hey All,
We have bit of a riddle and I thought I would ask here about your thoughts.
We have this disk:
Rugged Triple USB 3 | LaCie Support US
Disk is fine, its cable - although not original one - has been USB 3.0-tested with another SAMSUNG or SEAGATE external disk. We also checked the other cable as well - all to no avail: It stubbornly gets recognised as USB 2.0-only device by Windows 10 on our company Surface Laptops - also confirmed by USB Tree View utility.
Disk firmware is up to date, we do use USB 3.0 port (straight or via hubs) that otherwise work fine with USB 3.0 devices.
We connected this disk to Mac laptop - ~41MB/s was all we could get - which implies USB 2.0 connection again (not sure if MacBook Pros have USB 3.0 ports - I think they do though?).
I reached LACIE and am awaiting their further update on this past the first not very helpful ideas (reformat the drive), but... Ideas?

Try connecting through a powered USB3.0 hub and make sure that the USB interface on the PC is blue not black.

Ha! That's a thought - have not thought about power (or lack thereof) possibly being a factor here.
We tried this on fancy corporate devices that may not have enough juice, rather than boring desktops with enough power in their sockets.
And yes, USB 3.0 ports only were tried.

USB power is divided by all ports with onboard adapters for desktops. Even with Macbooks, you may have to use a powered hub or USB dplitter that supplies power from another USB port to the device.

Well, Surface Laptop does have only one USB 3.0 port... But I can definitely see the rationale especially, as that disk is not really a very slim device.
Will report my findings tomorrow.

Make sure you're using a USB 3.0 cable (typically has a blue plastic piece inside)….
and that it's also plugged into a USB 3 / 3.1 port. Don't use a HUB unless it specifically supports USB 3 / 3.1 speeds. And again, you're using a USB 3 cable; and the hub is plugged into a USB 3 / 3.1 port.
In order to get USB 3 speeds both cable and port must support those. Anything less, and you'll get the slowest speed of the slowest item.
Good luck.

LACIE already confirmed that any after market USB 3.0 cable will do.
(Everything else has been confirmed by me in my original post)

Re-read my post... I never said "any after market USB 3.0 cable" wouldn't do. I said make sure (whatever brand cable) is USB 3 capable. Completely different statement.
And as a side note, even being a 3.0 cable, doesn't guarantee full USB 3.0 speeds. There are other factors at play, which is why device manufactures dealing in speed devices uses the phrase "up to".
Out.

item number: 301983 max speed 110mb/s
301982,301984,301985 max speed 80mb/s
if the disk is above 60% capacity used u can expect below avertised speeds.
Download usbtreeview and find out what usb protocol your disk use.

Likewise: LACIE already confirmed that any after market USB 3.0 cable will do.
Also, either connection (@ hardware layer) is established as USB 3.0, or it isn't and it drops to 2.0. There isn't any up to here.
(Which also has been verified with USB Tree View as High Speed only, about which I wrote in my first post)
