Tried setting the v10 on it too, but same results, libusb sees it, the scanimage program doesn't, makes me think libusb isn't playing nice. (I had problems using an old Palm Z22 device with libusb, had to revert to using the kernel 'visor' module..)  libusb-config --version 0.1.12

We do not provide Slackware packages on our site. How exactly did you install 
the non-free esci-interpreter-gt-f720 plugin package? It contains the 
proprietary library and firmware file required to get the V30 working.

 From your earlier mail you seem to have done all the setup manually. You will 
also need to add an interpreter line to epkowa.conf. In your case it should look 
something like this:
interpreter usb 0x04b8 0x0131 /usr/lib/esci/libesci-interpreter-gt-f720

Also make sure the firmware file for this model `esfw8b.bin` is located under 
/usr/share/esci/

Happy scanning,
