Your USB3 cable , provided with the Drobo, is most probably bad. I’m having right know exactly fhe same problem on my _ also_ brand new Drobo 5D. Device works perfectly with TB but USB3 cable will work only as USB2.
Just ask for another one
My new Drobo 5D works on the USB 3.0 port but only at USB 2.0 speeds. I tried switching out with a different cable but the same results. I have the USB 3.0 controller card updated with the latest drivers and also the latest firmware, but still the same.
Well this is an internal card, so you have to have some connector going to a port jack, just like any computer or laptop. Here it is: http://www.amazon.com/gp/product/B009WN7SQA/ref=oh_details_o07_s00_i01?ie=UTF8&psc=1
I’ve actually tried two different ones in addition to the two different USB 3.0 cables but it is the same behavior with the Drobo. Also, I have connected other USB 3.0 external drives like from Seagate and they all work perfectly at the USB 3.0 speeds and are recognized at USB 3.0 speeds. I used Parkdale to do test to confirm it.
Ok, yes, I have tried it on my other windows computer and it is recognized at 3.0 no problem. Still one never knows for sure, it is a problem with the Drobo or with the Renasas Chipset on the Syba card on my laptop. I’m sure both will claim to be following the specs to the letter. Anyway, thanks for your help.
Apologies to the OP on this thread, I did not mean to hijack it for my own problem. Just wanted to add some experience.
I’m having the exact same problem with Windows 8.1 and USB3 on an ASUS motherboard. USB3 works fine plugged into my Mac, but since the latest firmware update, it will not work on Windows, it won’t even detect the device. Works fine on USB2.
Today I installed a new Drobo 5D onto a Lenovo laptop with Windows 7 using the provided USB3 cable. The laptop would not recognize the Drobo. Rebooted everything - no change. Connected Drobo using a Monoprice USB3 cable and everyting works correctly. Reconnected with the provided cable and the laptop could not recognize the Drobo. In fact this time the error seemed to crash the USB service and I have to force a reboot of the laptop. Changed cable back to Monoprice cable and everything was fine again. Contacted Tech Support and the quickly agreed to exchange the cable.
hi richard, that sounds like a bad cable, it must have had too many kinks in it and snapped a wire or something.
hi josh, thats a bit worrying… do you have any other computer you can try the same drobo and cable on?
maybe a win7 machine, just to try and pinpoint whether the issue is the drobo/firmware/or win8 incompatibility?
hi dslam, try to give it some more time though, as with holiday season maybe the support teams got busy,
(a rather drastic option, ‘could’ be to make a full backup / image of your current windows, verified, and to then try upgrading some usb drivers to see… just be careful of any bios/motherboard updates as am not sure if all can be downgraded again)
