Issues with Homebrew browser/apps with USB drive
So I'm having trouble with the Homebrew browser and other apps when trying to load them from my USB thumb drives. I've tried two, Dane Elec 8GB flash drive, and SanDisk Cruzer 16GB flash drive. Both are compatible with the Wii (and both work just fine when loading backed up Wii games), and both have serious issues with trying to load Homebrew data. I can often get to the Homebrew browser from my USB thumb drives, but often freezes either when I try to download something, or even just after a few of the icons load (often freezes when it's on the 5th out of 527 or something). Also often have problems when I try to delete an app from the Homebrew channel. Are homebrew apps just generally not well suited for a USB flash drive, or is there something wrong with my programs?
Edit: Also another problem I've run into is *when* I do get a program to load successfully, once I go back to the Wii Homebrew channel, that and/or all the other programs will just...disappear from the menu. Loaded the flash drive onto my computer, looked into the apps folder, and the apps have actually been deleted! It's very odd. I also want to point out I also don't have any of these issues (or any issues at all really) when loading Homebrew with an SD(HC) card.
