I connected my newly purchased UGREEN Dual Bay dock to my M1 MBP with a Belkin USB-C to USB-A cable but the drives do not get detected. The port and cable are fine because it can detect my 1tb Transcend external HDD without problem. What is the problem?
MacBook Pro (2020 and later)
Does it show in About this Mac>System Report>Hardware>USB?
look for both the Dock and the drives.
If you are still on 12.0.1 try updating to 12.1 which was released 12/13/2021
Try booting to Safe Mode. That boot up takes minutes and clears caches and other things that may resolve your problem.

A lot of times just boot to Safe Mode followed by normal boot resolves problems.
It could be that the Dock is not compatible with Monterey
12.1 solved a lot of problems with USB devices that were present in 12.0.1
Are you connecting the dock directly (not through hub) to the Mac?
I have tried three different disks: Western Digital 2tb HDD (Purple), Transcend 256GB (SSD), Samsung 128GB (SSD). None of them show up. But they work fine with Catalina and Mojave.
I erased Monterey 12.1 and replaced it with the latest Big Sur. Sad to say, same result as Monterey 12.1.
It appears to me, the problem is not with Monterey but with Apple M1.
The question is, what shall I do??
The dock comes with a USB-B to USB-A cable; I connect this to the Mac with a USB-A to USB-C cable.
Btw, the dock uses a JMS561U chipset. I can't find documentation that says that either this is compatible or incompatible with M1 Apple chip.
Do you have another disk to try in the dock? Some disk do not work with Monterey.
No, it does not show up under About this Mac>System Report>Hardware>USB
Yes, 12.0.1 and I am wondering if going back to Big Sur is better (having read some complaints regarding Monterey elsewhere).
Yes, tried Safe Mode but without avail.
I just updated Monterey to 12.1. The UGREEN dual bay dock now shows up under System Report>Hardware>USB. But the problem is the HDD and SDD do not appear. Neither do they appear in Disk Utility. I have tried four separate HDD's or SDD's (Western Digital, Transcend and Samsung), to no avail.
Should I try Big Sur? If so, which version would be best? And where can I get it?
Further, the UGREEN dual bay dock and the HDD and SDD's works just fine in two other Macs -- MacBook Pro Mid-2012 running Catalina and MacBook Air 2013 running Mojave. It's just our M1 MBP with Monterey 12.1 that's giving us the problem.
