Not as as simple as it appears

[SIZE="5"][/I have tried several different methods to get the combination of Leef Access microusb cardreader, a second cardreader, SanDisk Ultra microSDXC UHS-I Card, 64GB, Titanium backup pro, TWRP pro, and Nexus 7 2013 rooted to work together. I was able to accomplish this with a SanDisk 32 FAT32 but not the SanDisk Ultra microSDXC UHS-I Card, 64GB. I have unzipped fuse-exfat-exfat-utils to the sdcard directory of the Nexus 7 2013. The Root Explorer app mounts as read/write but the Titanium backup pro app says the path SDcard/usbstorage/sda1 and SDcard/usbstorage/sda are not writable. I need a secure backup method. I did get TWRP PRO and Titanium pro backups using one microusb cardreader. Titanium backup pro did verify the fat32 backup. HELP!!!!
