ConnectTech WhiteHEAT 4 port converter
ConnectTech has been very forthcoming with information about their
device, including providing a unit to test with. This driver will end up
being fully supported.
device, including providing a unit to test with.
Current status:
The device's firmware is downloaded on connection, the new firmware
runs properly and all four ports are successfully recognized and connected.
Data can be sent and received through the device on all ports.
Hardware flow control needs to be implemented.
The driver is officially supported by Connect Tech Inc.

For any questions or problems with this driver, please contact Greg
Kroah-Hartman at greg@kroah.com
For any questions or problems with this driver, please contact

Say Y here if you want to connect an USBLCD to your computer's
USB port. The USBLCD is a small USB interface board for
alphanumeric LCD modules. See <http://www.usblcd.de> for more
information.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called usblcd.o. If you want to compile it as
a module, say M here and read <file:Documentation/modules.txt>.
