usb_host_mass_storage_simpletest.py take for ever, block a cp and kill tio #2

Just tested this, only had one usb stick, it sees it, gets stats, but can't mount it (block device doesn't exist). It also stalls (rather than errors) attempting to mount it if you change code.py and it therefore reruns the init code as part of re-running code.py - think that usb stick is really slow to mount/work. I then tried some inception level stuff and connected a T-DisplayS3 running circuitpython. It listed the files happily, and because I didn't notice it had stalled I assumed it had written hello.txt too. I then rebooted(or was it ctrl+d) rp2040 to see if the hello.txt was listed, but then failed to do something (presumable read hello.txt) with USB Pipe Error / Memory Error. Later tried a USB3 SD card reader, chucked on 1 bmp and a boot_log.txt and changed the example to read+print that boot_log.txt first, which works, then it stalls when trying to write file. Tagging @tannewt for an enjoyable test bed when playing with USB Host stuff as he said he might be looking at it this week. Leaving the write to attempt to complete ended up with the device disconnecting after a fewminutes and it reconnects as a broken usb device on windows (battery connected to feather to avoid low power over usb).

Minor update, although it could read boot_out.txt, when testing reading a bitmap (601k) it never finished, and eventually rebooted as a broken usb device BMP displaying code (rp2040 usb host feather + 3.5 cap touch screen with sd): # SPDX-FileCopyrightText: 2023 Tyeth Gundry for Adafruit Industries

This test will initialize the display using displayio and display

Sounds like I didn't implement everything needed. I can't remember exactly how I tested it. |

Hi, a small bump here. I have the same behavior with the example, I am unable to write to a file on my usb key. I can list all files but unable to write. After a while it crash the communication. |

Not sure what to report but here is what I did and observed.
I deployed
8.2.0-75-gc75640eb0on a Feather RP2040 USB Host.Then I added in /lib the library from:
And copied the simple_test from USB_Host_Mass_Storage to code.py
At that point I inserted a USB key and I started to get output, and a directory listing of the root of the USB key.
The USB key continued to blink, but there was no further output.
So at that point I took another terminal window and tried to copy over the simple_test from USB_Host_Descriptors on the Feather.
But that copy was stuck, and the prompt not coming back. The USB key was still blinking, then
tiotold me I was disconnected from the REPL. And in the other window, my cp command ended (but likely not successfully).At that point the USB key was still blinking, but the CP board was not visible from
discotoolanymore.I just tested a second time with a
cp CODE_OF_CONDUCT.md /media/dglaude/CIRCUITPY/and same scenariocpdoes not end andtiodisconnect.I don't have many USB key (mass storage) to try, but I will try again to see if it content specific.
Some output:
