Tradeoffs with an external USB Host:

The FPS-Tech USB Host provides an excellent alternative to external USB Host controllers. Advantages include:

Very low pin-count required for external PHY (as low as 3 pins!). External hosts require 20+ pins.
External PHYs are much cheaper than integrated external host controllers (32 cents vs. $10)
Reduced pin requirements lead to more localized on-chip signal routing
Small board real-estate requirements (3x3mm)
Out-of-box uClinux support!
Interfaces with readily available USB PHYs such as Fairchild USB1T11 Family and NXP ISP1105
