[solved] mounting pi pico drive: an operation is already pending

I've connected a raspberry pi pico to my system, and pressed both the reset and boot buttons of it. Now it presents itself as a drive.
Dmesg reports the new drive:

# dmesg -w

I'm running lxqt on Xorg. In the file utility, I do see the drive RPI-RP2. When I click on it I see the following popup:

Unable to access "RPI-RP2"
An operation is already pending

When I press reset on the raspberry pi pico, I see the following in dmesg

[42775.678649] usb 1-6.1.3.3: USB disconnect, device number 16

and the following popup:

Operation was cancelled

Next I click OK on both popups, and press reset-boot again on the pi pico. Now the above story repeats.

fdisk can see the drive:

# fdisk -l
Disk /dev/sdj: 128 MiB, 134217728 bytes, 262144 sectors
Disk model: RP2

Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x000ac21f

Device     Boot Start    End Sectors  Size Id Type
/dev/sdj1           1 262143  262143  128M  e W95 FAT16 (LBA)

What can I check?

Re: [solved] mounting pi pico drive: an operation is already pending

You're trying to use a RPi as a filesystem by connecting the USB on your Arch box to the USB on the RPi?  I was unaware that could be done at all.  Not what you asked by why not just remove the uSD card and connect it to a card reader on your Arch box?

Re: [solved] mounting pi pico drive: an operation is already pending

I made a typo in my post. It's not the raspberry pi (the single board computer), it's a raspberry pi pico (the RP2040 microcontroller).

The pi pico doesn't have a uSD card, it presents itself as a memory stick, so a uf2 file can be copied to it, containing the firmware for the microcontroller.

After a reboot, it works again. i don't know if there's a log that can give me a reason why it didn't work. Until it goes wrong again, this is solved.

Re: [solved] mounting pi pico drive: an operation is already pending

If you updated your kernel and didn't reboot yet then your kernel can't load modules which might be necessary for certain device access.
