For some reason this didn't come thru to the list. See Henry reply below.

Peripheral controller driver is a new kernel driver. 2, 3. CDC Ethernet and File-backed storage are patchs to existing kernel gadget files. 4. Linux utility includes 3 applications. The first one is client utilty. It runs in MID and provides options for user to select shared folder. The second one is host utility. It runs in USB host system and mounts the shared folder in MID. The third one is host installer. It installs the host utility to host system from MID. The host utility and host installer are saved in MID first. Mass storage gadget is first used to copy host utility from MID to host system. Then CDC-EEM/RNDIS gadget is used to set up network connection for file sharing. We are providing kernel driver and patchs. The utility is a sample to demonstrate how to use the USB client driver and a reference for further development as well.

Peripheral Controller Driver: This is the kernel driver I expected 2. CDC Ethernet: Doesn't this exist in the kernel already? 3. File-backed storage: Doesn't this exist in the kernel already? 4. Linux utility: What's this? I suspect that the two gadget drivers were colored blue (signifying from the diagram key that they are software components that need to be developed) on accident, but my real concern is the item labeled "Linux utility". The reason for my concern is that I can interpret the blueprint in two ways (given the extremely sparse text explainations.) One interpretation basically says: We are providing the kernel drivers needed so that it is possible to make a Poulsbo based MID running UME either look like a USB mass storage device, or like an Ethernet device, but that's all we are doing. All the rest of the job is left as an exercise to the person/organization building a specific solution. In other words if you install a stock UME image on a Poulsbo based mobile internet device, and then plug it into a PC's USB port, then nothing will happen. Another interpretation basically says: We are providing the kernel drivers needed so that it is possible to make a Poulsbo based MID running UME either look like a USB mass storage device, or like an Ethernet device, and in addition to this we are also providing a significant amount of user space tools and configurations so that if you install a stock UME image on a Poulsbo based mobile internet device, and then plug it into a PC's USB port, then <<INSERT CORRECT BEHAVIOR HERE>> BTW, I'm personally ok with the first interpretation, but if the second interpretation was the real intent then this spec needs a lot more content. That "Linux utility" component could be a magnitude more work then a simple peripheral kernel driver (depending what the utility really does.) --rusty ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Charles Johnson Sent: Wednesday, August 01, 2007 8:23 AM To: ubuntu-mobile@lists.ubuntu.com Subject: Re: USB Client Blueprint I have not seen any additional comments here.

The folks doing the work think they addressed the comments from the previous round. So if you still need more, please post them to the ubuntu-mobile lists again. Also this is another late driver. It isn't schededuled to be Alpha until 1st week of September. Way to late. I've asked them if they can provide an early copy so that we can get the packages written and debugged. Otherwise it will have to be in the Update. Henry - Please respond to the comments on the ubuntu-mobile@lists.ubuntu.com mailing list.
