Increasing usbcore.usbfs_memory_mb or decreasing the number/size of the buffers requested in rtlsdr_read_async fixes this for me.

Tested several rtl dongles with linux 3.9.1 on Debian Jessie (testing)
and got disappointing results
2 dongles simultaneously working ok
if using 3 or more than 3rd dongle not working (1st and 2nd working ok)

in Debian Wheezy i did manage to run 5 dongles simultaneously (kernel 3.2)
i suppose  developers should pay attention to than fact.
