The memory allocation heuristics in the usb driver provided by dde_linux
changed with the recent commit 71b2b42936.
Apparently, the new variant requires a larger memory pool. Increasing
the quota is a temporary fix until the memory allocator gets revisited.
The additional quota is needed because of the recent performance
optimizations of the USB/networking code, e.g., to support the
increased NIC packet-stream buffer size.
