Looking for some input on the following problem that I realized isn't really usb specific:
My goal is to display an html page that resides on a usb mass-storage device and changes over time. The mass-storage device will be read-only from the host OS, but needs to self modify its own data. The end-user will view an html page that periodically refreshes itself and hopefully changes over time. My concern is how caching in the host OS may hide these changes. The usb device's MCU is very small and doesn't have space for a FAT driver. To modify its data I was planning to just poke changes directly to hard-coded offsets (the files can be pre-allocated since data is not created, just modified). Perhaps I could also poke the FAT file date, but would that be enough to cause Linux to reload the file? Or will the kernel assume all changes to local file-systems must pass through the kernel and miss even that? Maybe there is a better approach? One big limitation is that nothing can be installed on the host. And I'll have to figure out Windows eventually as well.
