did anyone ever using this card reader?
the model is ugreen 50540
is that card reader support lock mode on the SDcard?

i have a problem to find card reader that really support lock mode on SDcard
i already bought 3 Card Reader from domestic brand to international brand like this ugreen model 50706 which looks like a USB stick:

www.ugreen-shop.co.uk

2-in-1 USB C OTG Card Reader

This 2-in-1 USB C OTG Card Reader supports super fast data transfer up to 5Gbps, 10X faster than USB 2.0, transfer HD movies, or files in just seconds.
www.ugreen-shop.co.uk www.ugreen-shop.co.uk

but all of them cannot support locked mode from SDcard, i mean when i set my SDcard into lock mode, my pc can still delete and write files on this SDcard using those card reader, my SDcard didn't broke, is still run fine because i try to do it the same lock mode and i put directly into my laptop that already have SDcard slot, it runs well and I can't delete aor write files to it, that's how it should be.

i ask this because i don't want to waste some money again to buy this device but do not run well, i mean i always have hundreds of photo order every day and need to ASAP move the file into my PC or my phone so i can share it into my cust, and i already ask my friend that using ugreen card reader(30333) but with different model, he using model with some sort of cable not like mine that using USB stick model for easy to use and easy to carry and he said his card reader is support with lock mode SDcard he can't delete or write files using that card reader, that's the feature i want to protect my files when i plug into my pc but i don't want that model because is a little big to carry on an not really comfort like usb stick model to plug into my phone

What procedure, process, screens are being used to set the SDcard into lock mode?

Did you load any drivers or supporting applications?

What format is being used?

From the link:

"the memory card file format should be FAT32/EXFAT, NTFS is not supported."

Because i try to use it in lock mode and plug in directly into my laptop that have SDcard slot and the SD card becomes read-only mode like it should be.

As I understand this thread thus far the objective is to find some difference between the Laptop and Desktop with regards to the SDCards "performance".

Laptop: SDcard (exfat) is locked and performs as expected - Read Only - correct?

Desktop: SDcard (exfat) is locked and allows Read and Write (not just the expected Read Only - correct?

Are both the Laptop and Desktop using the same SDCard reader driver? The documentation states that no driver is needed so I would expect that both systems are using some native Windows driver.

Check Device Manager on both systems. You could also check your friend's Ugreen reader.

What driver is listed for the SDCard Reader?

(Note: I am not a "chip" person per so will defer to those who are knowledgeable about the GL3223.)

Another way to compare the Laptop and Desktop is to use PowerShell.

You can use the Get-PNPDevice cmdlet as a starting point.

FYI:

https://learn.microsoft.com/en-us/p...evice/get-pnpdevice?view=windowsserver2022-ps

Output could be lengthy - that can be dealt with in other ways if and as necessary.

For now, the objective is simple to find some difference(s) between laptop and desktop with respect to the SDcard reader.

Look in the Class (USB) column and the Friendly Name (TBD) column for the card reader.

The next step being to delve deeper in to the card reader properties on the laptop and desktop and compare accordingly.

= = = =

Another possible direction being to compare the rights/and permissions regarding the card reader on the laptop or desktop.

yes correct
but i think that's not the problem after that what you explain about pnp driver
because i try to using my card reader(that doesn't support SDcard lock mode) on my laptop, it still same i mean it's still doesn't run my SDcard lock mode

this is what i suspect maybe the chip on the card reader that have an effect about this problem

and also i try your method here

Use gpedit - stay out of the registry.

it's only makes my card reader can't be read/open and my SDcard didn't read anyway by my PC
didn't appear any file or data, just appear empty drive icon
