\opening{Dear Sir,}

The Linux USB Special Interest Group aims to provide high quality functionality,
documentation and support for Universal Serial Bus (USB) on Linux and other
Open Source operating systems. The Linux USB Special Interest Group provides
support for a range of USB hosts (both UHCI and OHCI), hubs and devices. This
support is provided on Intel, PowerPC and Alpha processors, and development
and testing is ongoing.

The Linux USB Special Interest Group has previously focussed on support for
USB 1.1. With the public release of USB 2.0, support for
high speed devices is planned. To assist with support for USB 2.0, the
Linux USB Special Interest Group is seeking assistance from major hardware
vendors in some or all of the following areas:
\begin{itemize}
	\item Provision of programming information for vendor specific devices.
	\item Long term loans and donations of sample devices.
	\item Engineering assistance and donations of device driver code.
\end{itemize}

For further information on the Linux USB Special Interest Group, its work, and
how supporting open source can increase sales and reduce costs for your company,
please refer to the enclosed information.

If your company can provide assistance or requires further information,
please contact the Linux USB Special Interest Group.

\closing{Thank you for your time,}

\end{letter}
