Impossible to support USB Keyboards by PLoP

[VV2006]

Hi! Dear Elmar, thank You for a nice Tools! With a PLoP Boot Manager Version 5.0.7 speed of Booting from USB rises even on rapid BIOS (rose approximately twice)!

There is a Problem: аfter the Load of plpbt.bin Support of USB-Keyboard is lost and accordingly  impossible to choose some Option from GRUB4DOS menu.lst (booting proceeds by default and all is Ok). Is it possible somehow it to correct?

PLoP Boot Manager config:

Code: [Select]

plpcfgbt.exe stm=hidden cnt=on cntval=1 dbt=usb vm=text fnt=bios plpbt.bin
and GRUB4DOS menu.lst option:

Code: [Select]

title PLoP - fast USB speed
find --set-root --ignore-floppies /boot/plpbt.bin
kernel /boot/plpbt.bin
Addition these lines at the beginning of every option of menu is uncomfortable. Please help if You can!
