现象

Windows识别为mass storage但无盘符，Linux主机报xhci_drop_endpoint called with disabled endpoint

根因

帖中未明确

可尝试的处理步骤

• modprobe configfs
• modprobe libcomposite.ko
• modprobe usb_f_mass_storage.ko
• modprobe gadgetfs.ko
• dd if=/dev/zero of=/tmp/mydev count=500 bs=1M
• mount -t configfs none /sys/kernel/config
• cd /sys/kernel/config/usb_gadget
• mkdir g1
• cd g1
• echo "64" > bMaxPacketSize0
• echo "0x200" > bcdUSB
• echo "0x100" > bcdDevice
• echo "0x03FD" > idVendor
• echo "0x0501" > idProduct
• cat max_speed
• echo "high-speed" > max_speed
• mkdir functions/mass_storage.ms0
• mkdir configs/c1.1
• echo /tmp/mydev > functions/mass_storage.ms0/lun.0/file
• echo 1 > functions/mass_storage.ms0/lun.0/removable
• ln -s functions/mass_storage.ms0/ configs/c1.1/
