USB Drive IO error only with specific Computer/USB Drive combination
Please help. I cannot use my new 256GB DataTraveler Max USB 3.2 Gen 2 (USB A) on my laptop ASUS B9450 . It is very strange:
- On my other laptop and PC the USB drive works fine, on Windows and Linux, but on this one, neither on Windows nor on Linux it works.
- I ordered a second one but it is the same behavior, so I think my laptop USB port is broken.
- But all other USB drives I own are working on this laptop.
- On Windows when I plug it in, I hear the typical plugin sound and them shortly after the unplug sound, the USB folder opens but when I try to click anything, I get an error. Sometimes I can see a a correct thumbnail of a picture I have saved on the USB drive. But never I can access it without an error. This repeats again and again, a new file explorer window is opened each time but they are all useless.
- I can boot from the drive. I have used Ventoy to put several ISO, for example gparted. When I select it, it starts to boot but I see log messages (maybe I have a typo, I typed this from a photo)
Code:
[6.464954] usb 2-5: cmd cmplt err -108
[6.465216] I/O error, dev sda, sector 0 op 0x0:(READ) flags 0x80700 phys_seq 1 prio class 2
[6.465358] device offline error, dev sda, sector 0 op 0x0:(READ) flags 0x0 phys_seq 1 prio class 2
[6.465412] Buffer I/O error on dev sda, logical block 0, async page read
[6.465535] device offline error, dev sda, sector 0 op 0x0:(READ) flags 0x0 phys_seq 1 prio class 2
[6.465588] Buffer I/O error on dev sda, logical block 0, async page read
But then booting stops, this means I cannot really boot from the USB drive but it is recognized as bootable option and I get half-way through the booting process. This consistently happens every time I try.
- I have installed Linux Mint on this possibly faulty laptop, everything works fine but with this stick plugged in, I cannot boot normally, it repeatedly prints messages and booting finishes only when I unplug it:
During Mint boot with this stick it fills the screen with
ERROR: opening "/dev/sda"
And then every 3 seconds it prints some message "cmd cmplt err -108" and after 1 minute, it completed to boot.
Strangely then I could access the USB drive normally, this was an unusual observation while writing this. I could create a directory. After shutting down, I tried to repeat it but the next time it printed the "cmd cmplt err -108" only for around 30 seconds until it booted but now I cannot access the drive: In nautilus, when I try to click on the device partition to mount it, it says "cannot read superblock".
All this is very strange and I have no idea what is causing this issue. In total I have tested with 2 other older laptops and one PC they all have no problem accessing the USB drive. Maybe it has to do with USB 3.2? Please help, I now have 2 of these sticks. I have no second USB A port on this laptop.

USB devices receive both data and power from the USB port. The power available from a USB port is marginal. You can have problems on a USB port when you plug in a device which requires a lot of power or if you plug in several devices on a hub. I also get this problem on one of my computers which has two USB ports that are actually an internal hub.
From the symptoms that you describe I would guess that the USB port in question is putting out less power than the specs call for. Try running a low power USB device like a mouse or a keyboard in that port and see what happens.

Thank you. Unfortunately I don't have a hub. I tried a mouse and a keyboard and they work without problems. Even other (older 16GB) sticks work. Maybe your guess with the power consumption is correct. I have
Code:
usb-devices | grep 'Product=\|MxPwr'
S: Product=xHCI Host Controller
C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=0mA
S: Product=ELAN:Fingerprint
C: #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA
S: Product=xHCI Host Controller
C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=0mA
S: Product=DataTraveler Max
C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=896mA
from this answer https://unix.stackexchange.com/quest...f-a-usb-device tried on my OTHER laptop where I can use the stick normally. Is this 896mA a reliable information (measured or just reported maximum number by the device)? It seems right below the spec maximum which I read is 900mA for USB 3.0.
I could buy a thunderbolt to USB A adapter to check whether it works then.

I found an adapter from USB C to A and on the other two ports (both USB C), I can access the stick in both, Linux Mint and Windows.
