[Asus Transformer TF700] dCaptn:
External USB adapter not working

got the logcat working, thanks! :good:

...and this is what (a snip of) logcat looks like, when inserting / removing the external USB flash:

(I used notepad2 to edit the logcat)

is this something useful? (for the wise, of course :fingers-crossed: - for me it's like ...latin :D )

one more remark;

after noticing in logcat the string "usbdisk1", I tried again to access the external storage, using

ES File Explorer file manager https://play.google.com/store/apps/details?id=com.estrongs.android.pop

ES File Explorer does show "usbdisk1" after inserting external storage.

with the USB flash I was prompted for a permission to acces the storage, and then could use ES Explorer to create folders and files on the external storage, as well as copy files to the internal storage.

when attempting to open a file directly from the external storage, the other app (VLC) could not use the external storage.

(although ES file manager is trying to launch the app associated with that file type)

but with the external HD, no luck! ES file manager can see it connecting , but will not mount it.

(I could get another logcat for the external HD insert/remove, if that helps)
