IF/How can Linux access Win7-box via USB?

I had to buy [the cheapest possible] Win-device to access my
wireless-telephone/modem; which was also another disappointment.

This HP ??? is magnificently cost-effective technology, used to wrap the
crap of Win7: which is continually pushing unwanted stuff-in-your-face.

I'm not familiar with USB and here's my attempt to see into the Win7 files
via linux. I need to be able to d/l a sequence of http to an accumulating file,
like linux does with a script that repeatedly calls `lynx -dump <URL> >> AcmFile`.

-> boot NetBook
-> Boot Deb & plug usb lead to Netbook.
-> lsusb =Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
-> plug opto-mouse to deb
-> lsusb
Bus 001 Device 002: ID 15ca:00c3 Textech International Ltd. Mini Optical Mouse
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

=> NetBook ~ Computer = shows only 3 drives c,d,e

-> unplug USB-NetBook
-> lsusb ==
Bus 001 Device 002: ID 15ca:00c3 Textech International Ltd. Mini Optical Mouse
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

? so the 'hub' is NOT the NetBook ?

-> mount /dev/sda1 /media/USBstik =mount: you must specify the filesystem type

/dev/sda2 1091592 295400 740740 29% /media/USBstik

?? => /media/USBstik seems to contain a Deb-system ??
-> cfdisk /dev/sda1 =sda1 Primary W95 FAT32 800.46
sda2 Primary Linux ext3 1259.61

-> copy this file to /dev/sda1 for posting

Since both Win7 & linux can read/write a USBdevice, how do you get the two to
see each other as read/write USBdevices ?

== TIA.
