Subject: Heads-Up: two new USB to serial drivers
If you do not use USB to serial adapters, you can probably delete this message.
We have putback the following into Solaris Nevada ON gate in build 28 and 31:
6314504 Support for Prolific USB serial adapters
6314455 Support for Keyspan USB serial adapters
6357654 support keyspan 4 port USB serial adapter (49wlc)
Some background information:
- In the past only Digi edgeport USB serial adapters were supported, which
unfortunately had some user satisfaction issues. These putbacks extend the USB
serial support to two other vendors.
- 6314504 was putback to build 28 and introduced the usbsprl(7D) driver.
Prolific pl2303 chip set based adapters are supported. They are one port
adapters. Most of these adapters have the vendor ID and product ID as:
"usb67b,2303". To find out if your adapters have the same IDs, just plug it to
the usb port and check the dmesg, you will see the similar ID string.
And we also know some other adapters with different vendor ID and product ID are
also based on pl2303 chip set and can be supported by this driver. Such as Aten
UC-232A adapter, you can find it at: http://www.aten.com
We'll add its IDs to usbsprl's postinstall script soon.
- 6314455 was putback to build 28, and introduced the usbsksp(7D) driver. The
1-port Keyspan USA19HS adapter is supported. It can be found at:
http://www.keyspan.com/products/usb/USA19HS/
- 6357654 was putback to build 31 and enabled support in usbsksp driver for the
4-port Keyspan USA49WLC adapter and introduced a placeholder misc module
(usbs49_fw) for the adapter's firmware. Because of legal issues, we were not
allowed to include the real firmware module in Solaris. Therefore, to make this
device work, internal users need to download the firmware package (SUNWukspfw)
from the following links to replace the one installed by default. Your firmware
module will not be replaced when bfu'ing or upgrading your system.

or

External users can soon download the firmware package from the Keyspan's website
(http://www.keyspan.com).
Please refer to the above link for more information about the use of Keyspan USB
serial devices.
