Troubleshooting • USB hub and Pico BOOTSEL??

I have several USB hubs. I've recently discovered that at least one of them (I've only tested one so far) has a problem. I can plug a Pico W directly into a Linux computer with a cable holding down the BOOTSEL button and the Pico USB drive will show up in `lsusb` and as a disk drive. But if I plug the Pico cable into the USB hub and hold the BOOTSEL button while powering up the USB port on the hub, the Pico shows up as "boot" in `lsusb`, and `picotool` sees it in BOOTSEL mode, but there is no disk drive!

Can someone explain to me what is happening here? Is this some kind of Linux USB driver problem?
