Hi, all. I have an USB floppy drive which works well on 7.1-RELEASE, and 8-current with the old USB stack. ***** umass0: <Y-E DATA USB Floppy Drive, class 0/0, rev 1.10/5.01, addr 2> on uhub0 da0 at umass-sim0 bus 0 target 0 lun 0 da0: <Y-E DATA USB-FDU 5.01> Removable Direct Access SCSI-0 device da0: 20KB/s transfers da0: Attempt to query device size failed: NOT READY, Medium not present port 1 addr 2: full speed, power 500 mA, config 1, USB Floppy Drive(0x0000), Y-E DATA(0x057b), rev 5.01 ***** When I connect the floppy drive to the system with the new USB2 stack, it causes a kernel panic. Here is a stack trace and dmesg output. capricorn# kgdb /boot/kernel/kernel.symbols /var/crash/vmcore.0 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
