Is that not what the hub is for?

Thanks for the reply.
I just got USB Complete. 1 more question. I am planning to utilize 4 usb
slots. However, PIC32 has only 1 USB slot. Can I just tap the 3 slots in
the bus? or their is better solution?

Get a copy of Jan Axelson's "USB Complete" and read that.  Unless 
Microchip have provided a reasonably full implementation of a USB host 
you have a fair amount of work ahead of you:  USB host driver, HUB 
driver, MSC host side driver, SCSI driver, FAT/NTFS driver.  A HUB 
driver need not be particularly complicated but a full USB host is quite 
a lot of work ...

Are you doing this commercially, if so consider one of the embedded host 
implementations.

Hi dz,

I have read about a few projects like this on some forums. The concensus I 
believe is that the USB Host stack that is supplied free will only 
communicate with a single device and that the hub class and associated 
complexities of multiple attached devices are not included.

As far as I am aware, the only full USB Host stack for the PIC32 is from 
HCC-Embedded. It isn't free

Hope this helps.

No problem, just get some software that does.  Or is your USB host  
implemented in an FPGA?

You didn't provide much information to base useful suggestions upon.

No, I will not accept blessings from any of your gods.  Please have them  
returned to the appropriate deity.  And besides, mythology is off-topic  
here.

Hi,
I am currently working on a embedded host for USB thumb drives using PIC32
starter kit. Unfortunately, the embedded host does not support  USB hubs. I
am planning to transfer files between multiple thumb drives. Can anyone
help me or give suggestions.
Thank you in advance. God Bless.
