Для этого бывают специальные "кабели", которые далеко не просто
кабели; там должен стоять чип, который с обеих сторон будет выглядеть
как USB-устройство.  В Linux поддерживаются некоторые типы этих
кабелей - например, драйвером usbnet:

/*
 * This is used for "USB networking", connecting USB hosts as peers.
 *
 * It can be used with USB "network cables", for IP-over-USB communications;
 * Ethernet speeds without the Ethernet.  USB devices (including some PDAs)
 * can support such links directly, replacing device-specific protocols
 * with Internet standard ones.
 *
 * The links can be bridged using the Ethernet bridging (net/bridge)
 * support as appropriate.  Devices currently supported include:
 *
 *	- AnchorChip 2720
 *	- Belkin, eTEK (interops with Win32 drivers)
 *	- EPSON USB clients
 *	- GeneSys GL620USB-A
 *	- NetChip 1080 (interoperates with NetChip Win32 drivers)
 *	- Prolific PL-2301/2302 (replaces "plusb" driver)
 *	- PXA-250 or SA-1100 Linux PDAs like iPAQ, Yopy, and Zaurus
 *
 * USB devices can implement their side of this protocol at the cost
 * of two bulk endpoints; it's not restricted to "cable" applications.
 * See the SA1110, Zaurus, or EPSON device/client support in this driver;
 * slave/target drivers such as "usb-eth" (on most SA-1100 PDAs) are
 * used inside USB slave/target devices.
