I am using a generic USB-to-serial adapter based on an FTDI232 chip. Until now it was presented as a ttyUSB device (after loading the ftdi_sio module using sudo modprobe ftdi_sio).
Now (running Fedora 6.19.8-200.fc43.x86_64) this did not work anymore. The device was shown as /usbmisc/lpvo_raw0 (usbmisc).
After some research I found out that removing the usb_gpib module (sudo modprobe -r lpvo_usb_gpib) and loading ftdi_sio restored the old status (making the FTDI hardware visible as /dev/ttyUSB1 (usb-serial).
Is this related to the introduction of some kind of GPIB functionality in Linux 6.19?
And should I blacklist the lpvo_usb_gpib module in /etc/modprobe.d?
