Micro SD USB for R4DS?

My friend gave me r4 for ds, but “forgot”to include the USB, and when i asked him about it, he said he lost it, so im wondering, would this work, so i could put more games on it. Optex Mobile Memory Card Reader Micro SD/SDHC/M2

Things I got from him:
R4 Cartridge
SanDisk Micro SDHC (8g)
