Update I re-flashed (serial console) one of my Pineapple iVs to 2.0.0 with a 16GB Sandisk Cruiser Fit in the pineapple during the re-flash
The 16GB drive has 3 Partitions: 2 Data, 1 Swap
In this instance the usb drive partitions were detected properly and the devices were numerated properly
I did have to run "mkswap /dev/sda3" and update the fstab to support the two usb data partitions usb = /dev/sda1 usb2 = /dev/sda2 swap = /dev/sda3
fstab is as follows:
config global automount
option from_fstab 1
option anon_mount 1
config global autoswap
option from_fstab 1
option anon_swap 1
config mount
option target /usb
option device /dev/sda1
option fstype ext4
option options rw,sync
option enabled 1
option enabled_fsck 0
config mount
option target /usb2
option device /dev/sda2
option fstype ext4
option options rw,sync
option enabled 1
option enabled_fsck 0
config swap
option device /dev/sda3
option enabled 1
