TMI completed these driver changes of a year ago and has since been maintaining
it. Silicon Labs was to push these changes through to the mainline kernel, but
-this clearly has not happened yet. TMI will be working directly with the kernel
-cp210x maintainer to investigate incorporating our changes. Meanwhile, TMI
-will continue to maintain its branch of the cp210x driver. The
-`cp210x-module-dkms` package in the APT repository has been tested on Ubuntu
-Hardy and Karmic systems with both 32 and 64 bit x86 (Intel/AMD) processors.
+this clearly has not happened yet. TMI has had some discussions with the
+linux-usb developers, and a decent number of changes need to be made before they
+will include our modifications upstream. Specifically, they want to see all
+ioctl calls replaced with other mechanisms. We hope to allocate some time to
+work on these issues in the future. Meanwhile, TMI will continue to maintain
+its branch of the cp210x driver. The `cp210x-module-dkms` package in the APT
+repository has been tested on Ubuntu 8.04 LTS (Hardy Heron), 9.10 (Karmic
+Koala), 10.04 LTS (Lucid Lynx), 10.10 (Maverick Meerkat), 11.04 (Natty Narwhal),
+and (soon) 12.04 (Precise Pangolin) systems, having both 32 and 64 bit x86
+(Intel/AMD) processors.
+
+Note: Silicon Labs has introduced new USB/Serial chips, like the cp2104. This
+driver is not compatible with the new parts.
