USB ethernet driver in developmentPublished: 24th Jun 2006, 22:37:34 | Permalink | Printable
Could offer support for USB cable modems [Updated]Using an ethernet network over USB on RISC OS will be possible thanks to a new driver in development. Programmer James Peacock has produced a USB Ethernet driver module, and says he will open source it. USB Ethernet devices basically allow computers to turn a USB port into a network socket.
The Avalanche VNC client author said: "I have my USB ethernet driver functioning at last - I can browse drobe.co.uk and so on."
James, an Iyonix owner, has written his software for the Castle USB stack, and it should support a chipset found in most USB ethernet products. His work paves the way for support for USB-only cable and ADSL modems, used for high speed Internet access.
He said: "The driver will currently talk to a AX88172 chip which supports 10Mb or 100Mb, although the best I've managed is about 20Mb so far and this was intermittent.
"It has been written to allow different 'backends' to be added to support other hardware - most of the Network DCI and USB ickyness is done now, so adding support for other chips should be relatively easy; CDC ethernet (as specified by the USB people and used by some cable modems) would seem high one the list."
The driver module still requires some tidying up and a few USB issues need resolving, according to James, who believes a public release 'make take a while'.
He added: "This chip is used in loads of devices apparently, though I've only tested it with a SiteCom part. It currently works fairly reliably - I used it for a couple of days instead of my on-board ethernet."
